- * This driver implements the bus-specific part of the i2400m for

- *
- * ARCHITECTURE
- *
- * This driver sits under the bus-generic i2400m driver, providing the
- * connection to the device.
- *
- * When probed, all the function pointers are setup and then the
- * bus-generic code called. The generic driver will then use the
- * provided pointers for uploading firmware (i2400ms_bus_bm*() in
- * sdio-fw.c) and then setting up the device (i2400ms_dev_*() in
- * sdio.c).
- *
- * Once firmware is uploaded, TX functions (sdio-tx.c) are called when
- * data is ready for transmission in the TX fifo; then the SDIO IRQ is
- * fired and data is available (sdio-rx.c), it is sent to the generic
- * driver for processing with i2400m_rx.

- * THE PROCEDURE
- *
- * See fw.c for the generic description of this procedure.
- *
- * This file implements only the SDIO specifics. It boils down to how
- * to send a command and waiting for an acknowledgement from the
- * device.
- *
- * All this code is sequential -- all i2400ms_bus_bm_*() functions are
- * executed in the same thread, except i2400ms_bm_irq() [on its own by
- * the SDIO driver]. This makes it possible to avoid locking.
- *
- * COMMAND EXECUTION
- *
- * The generic firmware upload code will call i2400m_bus_bm_cmd_send()
- * to send commands.
- *
- * The SDIO devices expects things in 256 byte blocks, so it will pad
- * it, compute the checksum (if needed) and pass it to SDIO.
- *
- * ACK RECEPTION
- *
- * This works in IRQ mode -- the fw loader says when to wait for data
- * and for that it calls i2400ms_bus_bm_wait_for_ack().
- *
- * This checks if there is any data available (RX size > 0); if not,
- * waits for the IRQ handler to notify about it. Once there is data,
- * it is read and passed to the caller. Doing it this way we don't
- * need much coordination/locking, and it makes it much more difficult
- * for an interrupt to be lost and the wait_for_ack() function getting
- * stuck even when data is pending.

-/************************** EEPROM BANDS ****************************
- *
- * The iwl_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel.  We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware.  This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel.  There is no corresponding channel information for that
- * entry.

- * Hardware Abstraction Layer for iwm.
- *
- * This file mostly defines an abstraction API for
- * sending various commands to the target.
- *
- * We have 2 types of commands: wifi and non-wifi ones.
- *
- * - wifi commands:
- *   They are used for sending LMAC and UMAC commands,
- *   and thus are the most commonly used ones.
- *   There are 2 different wifi command types, the regular
- *   one and the LMAC one. The former is used to send
- *   UMAC commands (see UMAC_CMD_OPCODE_* from umac.h)
- *   while the latter is used for sending commands to the
- *   LMAC. If you look at LMAC commands you'll se that they
- *   are actually regular iwlwifi target commands encapsulated
- *   into a special UMAC command called UMAC passthrough.
- *   This is due to the fact the host talks exclusively
- *   to the UMAC and so there needs to be a special UMAC
- *   command for talking to the LMAC.
- *   This is how a wifi command is laid out:
- *    ------------------------
- *   | iwm_udma_out_wifi_hdr  |
- *    ------------------------
- *   | SW meta_data (32 bits) |
- *    ------------------------
- *   | iwm_dev_cmd_hdr        |
- *    ------------------------
- *   | payload                |
- *   | ....                   |
- *
- * - non-wifi, or general commands:
- *   Those commands are handled by the device's bootrom,
- *   and are typically sent when the UMAC and the LMAC
- *   are not yet available.
- *    *   This is how a non-wifi command is laid out:
- *    ---------------------------
- *   | iwm_udma_out_nonwifi_hdr  |
- *    ---------------------------
- *   | payload                   |
- *   | ....                      |
-
- *
- * All the commands start with a UDMA header, which is
- * basically a 32 bits field. The 4 LSB there define
- * an opcode that allows the target to differentiate
- * between wifi (opcode is 0xf) and non-wifi commands
- * (opcode is [0..0xe]).
- *
- * When a command (wifi or non-wifi) is supposed to receive
- * an answer, we queue the command buffer. When we do receive
- * a command response from the UMAC, we go through the list
- * of pending command, and pass both the command and the answer
- * to the rx handler. Each command is sent with a unique
- * sequence id, and the answer is sent with the same one. This
- * is how we're supposed to match an answer with its command.
- * See rx.c:iwm_rx_handle_[non]wifi() and iwm_get_pending_[non]wifi()
- * for the implementation details.

- * iwm Tx theory of operation:
- *
- * 1) We receive a 802.3 frame from the stack
- * 2) We convert it to a 802.11 frame [iwm_xmit_frame]
- * 3) We queue it to its corresponding tx queue [iwm_xmit_frame]
- * 4) We schedule the tx worker. There is one worker per tx
- *    queue. [iwm_xmit_frame]
- * 5) The tx worker is scheduled
- * 6) We go through every queued skb on the tx queue, and for each
- *    and every one of them: [iwm_tx_worker]
- *    a) We check if we have enough Tx credits (see below for a Tx
- *       credits description) for the frame length. [iwm_tx_worker]
- *    b) If we do, we aggregate the Tx frame into a UDMA one, by
- *       concatenating one REPLY_TX command per Tx frame. [iwm_tx_worker]
- *    c) When we run out of credits, or when we reach the maximum
- *       concatenation size, we actually send the concatenated UDMA
- *       frame. [iwm_tx_worker]
- *
- * When we run out of Tx credits, the skbs are filling the tx queue,
- * and eventually we will stop the netdev queue. [iwm_tx_worker]
- * The tx queue is emptied as we're getting new tx credits, by
- * scheduling the tx_worker. [iwm_tx_credit_inc]
- * The netdev queue is started again when we have enough tx credits,
- * and when our tx queue has some reasonable amout of space available
- * (i.e. half of the max size). [iwm_tx_worker]

- * Since we're on an SDIO or USB bus, we are not sharing memory
- * for storing to be transmitted frames. The host needs to push
- * them upstream. As a consequence there needs to be a way for
- * the target to let us know if it can actually take more TX frames
- * or not. This is what Tx credits are for.
- *
- * For each Tx HW queue, we have a Tx pool, and then we have one
- * unique super pool (spool), which is actually a global pool of
- * all the UMAC pages.
- * For each Tx pool we have a min_pages, a max_pages fields, and a
- * alloc_pages fields. The alloc_pages tracks the number of pages
- * currently allocated from the tx pool.
- * Here are the rules to check if given a tx frame we have enough
- * tx credits for it:
- * 1) We translate the frame length into a number of UMAC pages.
- *    Let's call them n_pages.
- * 2) For the corresponding tx pool, we check if n_pages +
- *    pool->alloc_pages is higher than pool->min_pages. min_pages
- *    represent a set of pre-allocated pages on the tx pool. If
- *    that's the case, then we need to allocate those pages from
- *    the spool. We can do so until we reach spool->max_pages.
- * 3) Each tx pool is not allowed to allocate more than pool->max_pages
- *    from the spool, so once we're over min_pages, we can allocate
- *    pages from the spool, but not more than max_pages.
- *
- * When the tx code path needs to send a tx frame, it checks first
- * if it has enough tx credits, following those rules. [iwm_tx_credit_get]
- * If it does, it then updates the pool and spool counters and
- * then send the frame. [iwm_tx_credit_alloc and iwm_tx_credit_dec]
- * On the other side, when the UMAC is done transmitting frames, it
- * will send a credit update notification to the host. This is when
- * the pool and spool counters gets to be decreased. [iwm_tx_credit_inc,
- * called from rx.c:iwm_ntf_tx_credit_update]

 AI Triggering:
    For start_src == TRIG_EXT, the A/D EXTERNAL TRIGGER IN (pin 45) is used.
    For 1602 series, the start_arg is interpreted as follows:
-     start_arg == 0                   => gated triger (level high)
-     start_arg == CR_INVERT           => gated triger (level low)
+     start_arg == 0                   => gated trigger (level high)
+     start_arg == CR_INVERT           => gated trigger (level low)
      start_arg == CR_EDGE             => Rising edge
      start_arg == CR_EDGE | CR_INVERT => Falling edge
    For the other boards the trigger will be done on rising edge

+
+    NAME
+        CsrLogLevelTextSet
+
+    DESCRIPTION
+        Set the text logging level for a given origin and optionally sub origin
+        by name. If either string is NULL or zero length, it is interpreted as
+        all origins and/or all sub origins respectively. If originName is NULL
+        or zero length, subOriginName is ignored.
+
+        Passing NULL or zero length strings in both originName and subOriginName
+        is equivalent to calling CsrLogLevelTextSetAll, and overrides all
+        previous filter configurations for all origins and sub origins.
+
+        Passing NULL or a zero length string in subOriginName overrides all
+        previous filter configurations for all sub origins of the specified
+        origin.
+
+        Note: the supplied strings may be accessed after the function returns
+        and must remain valid and constant until CsrLogDeinit is called.
+
+        Note: when specifying an origin (originName is not NULL and not zero
+        length), this function can only be used for origins that use the
+        csr_log_text_2.h interface for registration and logging. Filtering for
+        origins that use the legacy csr_log_text.h interface must be be
+        configured using the legacy filter configuration functions that accept
+        a CsrLogTextTaskId as origin specifier. However, when not specifying an
+        origin this function also affects origins that have been registered with
+        the legacy csr_log_text.h interface. Furthermore, using this function
+        and the legacy filter configuration functions on the same origin is not
+        allowed.
+
+    PARAMETERS
+        originName - a string containing the name of the origin. Can be NULL or
+            zero length to set the log level for all origins. In this case, the
+            subOriginName parameter will be ignored.
+        subOriginName - a string containing the name of the sub origin. Can be
+            NULL or zero length to set the log level for all sub origins of the
+            specified origin.
+        warningLevelMask - The desired log level for the specified origin(s) and
+            sub origin(s).

+ * - Function ----------------------------------------------------------------
+ * card_hw_init()
+ *
+ *      Perform the initialisation procedure described in the UniFi Host
+ *      Interface Protocol document (section 3.3.8) and read the run-time
+ *      configuration information from the UniFi. This is stuff like number
+ *      of bulk data slots etc.
+ *
+ *      The card enumeration and SD initialisation has already been done by
+ *      the SDIO library, see card_sdio_init().
+ *
+ *      The initialisation is done when firmware is ready, i.e. this may need
+ *      to be called after a f/w download operation.
+ *
+ *      The initialisation procedure goes like this:
+ *       - Wait for UniFi to start-up by polling SHARED_MAILBOX1
+ *       - Find the symbol table and look up SLT_SDIO_SLOT_CONFIG
+ *       - Read the config structure
+ *       - Check the "SDIO initialised" flag, if not zero do a h/w reset and
+ *         start again
+ *       - Decide the number of bulk data slots to allocate, allocate them and
+ *         set "SDIO initialised" flag (and generate an interrupt) to say so.
+ *
+ * Arguments:
+ *      card        Pointer to card struct
+ *
+ * Returns:
+ *      CSR_RESULT_SUCEESS on success,
+ *      a CSR error code on failure
+ *
+ * Notes:
+ *      All data in the f/w is stored in a little endian format, without any
+ *      padding bytes. Every read from this memory has to be transformed in
+ *      host (cpu specific) format, before it is stored in driver's parameters
+ *      or/and structures. Athough unifi_card_read16() and unifi_read32() do perform
+ *      the convertion internally, unifi_readn() does not.

+ *  send_signal
+ *
+ *      This function queues a signal for sending to UniFi.  It first checks
+ *      that there is space on the fh_signal_queue for another entry, then
+ *      claims any bulk data slots required and copies data into them. Then
+ *      increments the fh_signal_queue write count.
+ *
+ *      The fh_signal_queue is later processed by the driver bottom half
+ *      (in unifi_bh()).
+ *
+ *      This function call unifi_pause_xmit() to pause the flow of data plane
+ *      packets when:
+ *        - the fh_signal_queue ring buffer is full
+ *        - there are less than UNIFI_MAX_DATA_REFERENCES (2) bulk data
+ *          slots available.
+ *
+ *  Arguments:
+ *      card            Pointer to card context structure
+ *      sigptr          Pointer to the signal to write to UniFi.
+ *      siglen          Number of bytes pointer to by sigptr.
+ *      bulkdata        Array of pointers to an associated bulk data.
+ *      sigq            To which from-host queue to add the signal.
+ *
+ *  Returns:
+ *      CSR_RESULT_SUCCESS on success
+ *      CSR_WIFI_HIP_RESULT_NO_SPACE if there were insufficient data slots or
+ *                              no free signal queue entry
+ *

+             * Since bh thread checks to unpause the queue *after* taking packets from the queue, we know that it is still going to make at
+             * least one more check to see whether it needs to unpause the queue.  So all is well.
+             * If there are no packets in the queue, then the deadlock described above might happen.  To make sure it does not, we

+ *
+ * Provides:
+ *      unifi_ta_sampling_init - Initialise the internal state
+ *      unifi_ta_sample        - Sampling function, call this for every data packet
+ *
+ * Calls these external functions which must be provided:
+ *      unifi_ta_indicate_sampling - Pass sample data to the SME.
+ *      unifi_ta_indicate_protocol - Report certain data packet types to the SME.

+    of the frame in question.
+    If the cancellation fails, the Router will send, if required,
+    CsrWifiRouterMaPacketCfm.
+    If the cancellation succeeds, the Router will not send
+    CsrWifiRouterMaPacketCfm.

+
+  NAME
+    CsrWifiSmeConnectReqSend
+
+  DESCRIPTION
+    The wireless manager application calls this primitive to start the
+    process of joining an 802.11 wireless network or to start an ad hoc
+    network.
+    The structure pointed by connectionConfig contains parameters describing
+    the network to join or, in case of an ad hoc network, to host or join.
+    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
+    and Associate exchanges.
+    The SME selects the networks from the current scan list that match both
+    the SSID and BSSID, however either or both of these may be the wildcard
+    value. Using this rule, the following operations are possible:
+      * To connect to a network by name, specify the SSID and set the BSSID to
+        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
+        the SME will select the one with the strongest signal.
+      * To connect to a specific network, specify the BSSID. The SSID is
+        optional, but if given it must match the SSID of the network. An empty
+        SSID may be specified by setting the SSID length to zero. Please note
+        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
+        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
+        poor, even if there is an alternative AP with an SSID that matches the
+        current network SSID.
+      * To connect to any network matching the other parameters (i.e. security,
+        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
+        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
+        by their signal strengths and will iterate through this list until it
+        successfully connects.
+    NOTE: Specifying the BSSID will restrict the selection to one specific
+    network. If SSID and BSSID are given, they must both match the network
+    for it to be selected. To select a network based on the SSID only, the
+    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
+    0xFF 0xFF.
+    The SME will try to connect to each network that matches the provided
+    parameters, one by one, until it succeeds or has tried unsuccessfully
+    with all the matching networks.
+    If there is no network that matches the parameters and the request allows
+    to host an ad hoc network, the SME will advertise a new ad hoc network
+    instead.
+    If the SME cannot connect, it will notify the failure in the confirm.

+  NAME
+    CsrWifiSmePacketFilterSetReqSend
+
+  DESCRIPTION
+    The wireless manager application should call this primitive to enable or
+    disable filtering of broadcast packets: uninteresting broadcast packets
+    will be dropped by the Wi-Fi chip, instead of passing them up to the
+    host.
+    This has the advantage of saving power in the host application processor
+    as it removes the need to process unwanted packets.
+    All broadcast packets are filtered according to the filter and the filter
+    mode provided, except ARP packets, which are filtered using
+    arpFilterAddress.
+    Filters are not cumulative: only the parameters specified in the most
+    recent successful request are significant.
+    For more information, see 'UniFi Firmware API Specification'.
+
+  PARAMETERS
+    queue            - Message Source Task Queue (Cfm's will be sent to this Queue)
+    interfaceTag     - Interface Identifier; unique identifier of an interface
+    filterLength     - Length of the filter in bytes.
+                       filterLength=0 disables the filter previously set
+    filter           - Points to the first byte of the filter provided, if any.

+                       information elements of one of these types

+                         * WMM-SA TCLAS elements
+    mode             - Specifies whether the filter selects or excludes packets
+                       matching the filter
+    arpFilterAddress - IPv4 address to be used for filtering the ARP packets.
+                         * If the specified address is the IPv4 broadcast address
+                           (255.255.255.255), all ARP packets are reported to the

+  DESCRIPTION
+    The wireless manager application calls this primitive to request an
+    operation on the SME PMKID list.
+    The action argument specifies the operation to perform.
+    When the connection is complete, the wireless manager application may
+    then send and receive EAPOL packets to complete WPA or WPA2
+    authentication if appropriate.
+    The wireless manager application can then pass the resulting encryption
+    keys using this primitive.

+
+  DESCRIPTION
+    The SME will send this primitive to all the tasks that have registered to

+    If the wireless manager application connect request specified the SSID
+    and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
+    0xFF), the SME monitors the signal quality and maintains a list of
+    candidates to roam to. When the signal quality of the current connection
+    falls below a threshold, and there is a candidate with better quality,
+    the SME will attempt to the candidate AP.
+    If the roaming procedure succeeds, the SME will also issue a Media
+    Connect indication to inform the wireless manager application of the
+    change.
+    NOTE: to prevent the SME from initiating roaming the WMA must specify the
+    BSSID in the connection request; this forces the SME to connect only to
+    that AP.
+    The wireless manager application can obtain statistics for roaming
+    purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
+    CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
+    When the wireless manager application wishes to roam to another AP, it
+    must issue a connection request specifying the BSSID of the desired AP.

+  NAME
+    CsrWifiSmeScanFullReqSend
+
+  DESCRIPTION
+    The wireless manager application should call this primitive to request a
+    full scan.
+    Channels are scanned actively or passively according to the requirement
+    set by regulatory domain.
+    If the SME receives this primitive while a full scan is going on, the new
+    request is buffered and it will be served after the current full scan is
+    completed.
+
+  PARAMETERS
+    queue            - Message Source Task Queue (Cfm's will be sent to this Queue)
+    ssidCount        - Number of SSIDs provided.
+                       If it is 0, the SME will attempt to detect any network
+    ssid             - Points to the first SSID provided, if any.
+    bssid            - BSS identifier.
+                       If it is equal to FF-FF-FF-FF-FF, the SME will listen for
+                       messages from any BSS.
+                       If it is different from FF-FF-FF-FF-FF and any SSID is
+                       provided, one SSID must match the network of the BSS.
+    forceScan        - Forces the scan even if the SME is in a state which would
+                       normally prevent it (e.g. autonomous scan is running).
+    bssType          - Type of BSS to scan for

+    channelListCount - Number of channels provided.
+                       If it is 0, the SME will initiate a scan of all the
+                       supported channels that are permitted by the current
+                       regulatory domain.

+                       is zero.
+    probeIeLength    - Length of the information element in bytes to be sent
+                       with the probe message.
+    probeIe          - Points to the first byte of the information element to be

+
+  NAME
+    CsrWifiSmeTspecReqSend
+
+  DESCRIPTION
+    The wireless manager application should call this primitive to use the
+    TSPEC feature.
+    The chip supports the use of TSPECs and TCLAS for the use of IEEE
+    802.11/WMM Quality of Service features.
+    The API allows the wireless manager application to supply a correctly
+    formatted TSPEC and TCLAS pair to the driver.
+    After performing basic validation, the driver negotiates the installation
+    of the TSPEC with the AP as defined by the 802.11 specification.
+    The driver retains all TSPEC and TCLAS pairs until they are specifically
+    removed.
+    It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
+    indicate that no TCLAS is supplied), while a TCLASS always require a
+    TSPEC.
+    The format of the TSPEC element is specified in 'WMM (including WMM Power
+    Save) Specification - Version 1.1' and 'ANSI/IEEE Std 802.11-REVmb/D3.0'.
+    For more information, see 'UniFi Configuring WMM and WMM-PS'.

+
+  NAME
+    CsrWifiSmeWifiFlightmodeReqSend
+
+  DESCRIPTION
+    The wireless manager application may call this primitive on boot-up of
+    the platform to ensure that the chip is placed in a mode that prevents
+    any emission of RF energy.
+    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
+    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
+    (if any) and the programming of the initial MIB settings (if supplied by
+    the WMA), but it also ensures that the chip is left in its lowest
+    possible power-mode with the radio subsystems disabled.
+    This feature is useful on platforms where power cannot be removed from
+    the chip (leaving the chip not initialised will cause it to consume more
+    power so calling this function ensures that the chip is initialised into
+    a low power mode but without entering a state where it could emit any RF
+    energy).
+    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
+    stays conceptually off. Configuration primitives can be sent after
+    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
+    Requests that require the state of the Wi-Fi to be ON will return
+    CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.
+
+  PARAMETERS
+    queue         - Message Source Task Queue (Cfm's will be sent to this Queue)
+    address       - Optionally specifies a station MAC address.
+                    In normal use, the manager should set the address to 0xFF
+                    0xFF 0xFF 0xFF 0xFF 0xFF, which will cause the chip to use
+                    the MAC address in the MIB.
+    mibFilesCount - Number of provided data blocks with initial MIB values
+    mibFiles      - Points to the first data block with initial MIB values.
+                    These data blocks are typically the contents of the provided
+                    files ufmib.dat and localmib.dat, available from the host
+                    file system, if they exist.
+                    These files typically contain radio tuning and calibration
+                    values.
+                    More values can be created using the Host Tools.

+
+  NAME
+    CsrWifiSmeWifiOnReqSend
+
+  DESCRIPTION
+    The wireless manager application calls this primitive to turn on the
+    Wi-Fi chip.
+    If the Wi-Fi chip is currently off, the SME turns the Wi-Fi chip on,
+    downloads the patch file (if any), and programs the initial MIB settings
+    (if supplied by the WMA).
+    The patch file is not provided with the SME API; its downloading is
+    automatic and handled internally by the system.
+    The MIB settings, when provided, override the default values that the
+    firmware loads from EEPROM.
+    If the Wi-Fi chip is already on, the SME takes no action and returns a
+    successful status in the confirm.
+
+  PARAMETERS
+    queue         - Message Source Task Queue (Cfm's will be sent to this Queue)
+    address       - Optionally specifies a station MAC address.
+                    In normal use, the manager should set the address to 0xFF
+                    0xFF 0xFF 0xFF 0xFF 0xFF, which will cause the chip to use
+                    the MAC address in the MIB
+    mibFilesCount - Number of provided data blocks with initial MIB values
+    mibFiles      - Points to the first data block with initial MIB values.
+                    These data blocks are typically the contents of the provided
+                    files ufmib.dat and localmib.dat, available from the host
+                    file system, if they exist.
+                    These files typically contain radio tuning and calibration
+                    values.
+                    More values can be created using the Host Tools.

+
+  NAME
+    CsrWifiSmeConnectReq
+
+  DESCRIPTION
+    The wireless manager application calls this primitive to start the
+    process of joining an 802.11 wireless network or to start an ad hoc
+    network.
+    The structure pointed by connectionConfig contains parameters describing
+    the network to join or, in case of an ad hoc network, to host or join.
+    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
+    and Associate exchanges.
+    The SME selects the networks from the current scan list that match both
+    the SSID and BSSID, however either or both of these may be the wildcard
+    value. Using this rule, the following operations are possible:
+      * To connect to a network by name, specify the SSID and set the BSSID to
+        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
+        the SME will select the one with the strongest signal.
+      * To connect to a specific network, specify the BSSID. The SSID is
+        optional, but if given it must match the SSID of the network. An empty
+        SSID may be specified by setting the SSID length to zero. Please note
+        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
+        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
+        poor, even if there is an alternative AP with an SSID that matches the
+        current network SSID.
+      * To connect to any network matching the other parameters (i.e. security,
+        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
+        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
+        by their signal strengths and will iterate through this list until it
+        successfully connects.
+    NOTE: Specifying the BSSID will restrict the selection to one specific
+    network. If SSID and BSSID are given, they must both match the network
+    for it to be selected. To select a network based on the SSID only, the
+    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
+    0xFF 0xFF.
+    The SME will try to connect to each network that matches the provided
+    parameters, one by one, until it succeeds or has tried unsuccessfully
+    with all the matching networks.
+    If there is no network that matches the parameters and the request allows
+    to host an ad hoc network, the SME will advertise a new ad hoc network
+    instead.
+    If the SME cannot connect, it will notify the failure in the confirm.

+    TSPEC feature.
+    The chip supports the use of TSPECs and TCLAS for the use of IEEE
+    802.11/WMM Quality of Service features.
+    The API allows the wireless manager application to supply a correctly
+    formatted TSPEC and TCLAS pair to the driver.
+    After performing basic validation, the driver negotiates the installation
+    of the TSPEC with the AP as defined by the 802.11 specification.
+    The driver retains all TSPEC and TCLAS pairs until they are specifically
+    removed.
+    It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
+    indicate that no TCLAS is supplied), while a TCLASS always require a
+    TSPEC.
+    The format of the TSPEC element is specified in 'WMM (including WMM Power
+    Save) Specification - Version 1.1' and 'ANSI/IEEE Std 802.11-REVmb/D3.0'.
+    For more information, see 'UniFi Configuring WMM and WMM-PS'.

+  NAME
+    CsrWifiSmeWifiFlightmodeReq
+
+  DESCRIPTION
+    The wireless manager application may call this primitive on boot-up of
+    the platform to ensure that the chip is placed in a mode that prevents
+    any emission of RF energy.
+    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
+    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
+    (if any) and the programming of the initial MIB settings (if supplied by
+    the WMA), but it also ensures that the chip is left in its lowest
+    possible power-mode with the radio subsystems disabled.
+    This feature is useful on platforms where power cannot be removed from
+    the chip (leaving the chip not initialised will cause it to consume more
+    power so calling this function ensures that the chip is initialised into
+    a low power mode but without entering a state where it could emit any RF
+    energy).
+    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
+    stays conceptually off. Configuration primitives can be sent after
+    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
+    Requests that require the state of the Wi-Fi to be ON will return
+    CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.

+    receive it whenever it begins an attempt to roam to an AP.
+    If the wireless manager application connect request specified the SSID
+    and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
+    0xFF), the SME monitors the signal quality and maintains a list of
+    candidates to roam to. When the signal quality of the current connection
+    falls below a threshold, and there is a candidate with better quality,
+    the SME will attempt to the candidate AP.
+    If the roaming procedure succeeds, the SME will also issue a Media
+    Connect indication to inform the wireless manager application of the
+    change.
+    NOTE: to prevent the SME from initiating roaming the WMA must specify the
+    BSSID in the connection request; this forces the SME to connect only to
+    that AP.
+    The wireless manager application can obtain statistics for roaming
+    purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
+    CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
+    When the wireless manager application wishes to roam to another AP, it
+    must issue a connection request specifying the BSSID of the desired AP.

+/*
+ * Porting Notes:
+ * Part of this file contains an example for how to glue the OS layer
+ * with the HIP core lib, the SDIO glue layer, and the SME.
+ *
+ * When the unifi_sdio.ko modules loads, the linux kernel calls unifi_load().
+ * unifi_load() calls uf_sdio_load() which is exported by the SDIO glue
+ * layer. uf_sdio_load() registers this driver with the underlying SDIO driver.
+ * When a card is detected, the SDIO glue layer calls register_unifi_sdio()
+ * to pass the SDIO function context and ask the OS layer to initialise
+ * the card. register_unifi_sdio() allocates all the private data of the OS
+ * layer and calls uf_run_unifihelper() to start the SME. The SME calls
+ * unifi_sys_wifi_on_req() which uses the HIP core lib to initialise the card.

+ *      UniFi card is first inserted (or detected) and removed.
+ *
+ *      When used with sdioemb, the udev scripts (at least on Ubuntu) don't
+ *      recognise a UniFi being added to the system. This is because sdioemb
+ *      does not register itself as a device_driver, it uses it's own code
+ *      to handle insert and remove.
+ *      To have Ubuntu recognise UniFi, edit /etc/udev/rules.d/85-ifupdown.rules
+ *      to change this line:
+ *          SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
+ *      to these:
+ *          #SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
+ *          SUBSYSTEM=="net", GOTO="net_start"
+ *
+ *      Then you can add a stanza to /etc/network/interfaces like this:

+ *          iface eth1 inet dhcp
+ *          wpa-conf /etc/wpa_supplicant.conf

+/*
+ * Porting Notes:
+ * This file implements the data plane of the UniFi linux driver.
+ *
+ * All the Tx packets are passed to the HIP core lib, using the
+ * unifi_send_signal() API. For EAPOL packets use the MLME-EAPOL.req
+ * signal, for all other use the MLME-UNITDATA.req. The unifi_send_signal()
+ * expects the wire-formatted (packed) signal. For convenience, in the OS
+ * layer we only use the native (unpacked) signal structures. The HIP core lib
+ * provides the write_pack() helper function to convert to the packed signal.
+ * The packet is stored in the bulk data of the signal. We do not need to
+ * allocate new memory to store the packet, because unifi_net_data_malloc()
+ * is implemented to return a skb, which is the format of packet in Linux.
+ * The HIP core lib frees the bulk data buffers, so we do not need to do
+ * this in the OS layer.
+ *
+ * All the Rx packets are MLME-UNITDATA.ind signals, passed by the HIP core lib
+ * in unifi_receive_event(). We do not need to allocate an skb and copy the
+ * received packet because the HIP core lib has stored in memory allocated by
+ * unifi_net_data_malloc(). Also, we can perform the 802.11 to Ethernet
+ * translation in-place because we allocate the extra memory allocated in
+ * unifi_net_data_malloc().
+ *
+ * If possible, the porting exercise should appropriately implement
+ * unifi_net_data_malloc() and unifi_net_data_free() to save copies between
+ * network and driver buffers.

+ * This file also contains the implementation of the asyncronous
+ * requests to the SME.
+ *
+ * Before calling an asyncronous SME function, we call sme_init_request()
+ * which gets hold of the SME semaphore and updates the request status.
+ * The semaphore makes sure that there is only one pending request to
+ * the SME at a time.
+ *
+ * Now we are ready to call the SME function, but only if
+ * sme_init_request() has returned 0.
+ *
+ * When the SME function returns, we need to wait
+ * for the reply. This is done in sme_wait_for_reply().
+ * If the request times-out, the request status is set to SME_REQUEST_TIMEDOUT
+ * and the sme_wait_for_reply() returns.
+ *
+ * If the SME replies in time, we call sme_complete_request().
+ * There we change the request status to SME_REQUEST_RECEIVED. This will
+ * wake up the process waiting on sme_wait_for_reply().
+ * It is important that we copy the reply data in priv->sme_reply
+ * before calling sme_complete_request().
+ *
+ * Handling the wext requests, we need to block
+ * until the SME sends the response to our request.
+ * We use the sme_init_request() and sme_wait_for_reply()
+ * to implement this behavior in the following functions:
+ * sme_mgt_wifi_on()
+ * sme_mgt_wifi_off()
+ * sme_mgt_scan_full()
+ * sme_mgt_scan_results_get_async()

+ *      Dispatcher for received signals.
+ *
+ *      This function receives the 'to host' signals and forwards
+ *      them to the unifi linux clients.
+ *
+ *  Arguments:
+ *      ospriv      Pointer to driver's private data.
+ *      sigdata     Pointer to the packed signal buffer.
+ *      siglen      Length of the packed signal.
+ *      bulkdata    Pointer to the signal's bulk data.
+ *
+ *  Returns:
+ *      None.
+ *
+ *  Notes:
+ *  The signals are received in the format described in the host interface
+ *  specification, i.e wire formatted. Certain clients use the same format
+ *  to interpret them and other clients use the host formatted structures.
+ *  Each client has to call read_unpack_signal() to transform the wire
+ *  formatted signal into the host formatted signal, if necessary.
+ *  The code is in the core, since the signals are defined therefore
+ *  binded to the host interface specification.

+ * we have followed this scheme:
+ * 1. If a function needs protection only when CSR_WIFI_SINGLE_FUNCTION is defined
+ *    then we call CsrSdioClaim/CsrSdioRelease().
+ * 2. If a function needs protection only when CSR_WIFI_SINGLE_FUNCTION is not defined
+ *    then we call _sdio_claim_host/_sdio_claim_host(). Use of this should be restricted
+ *    to the SDIO glue layer only (e.g. sdio_mmc.c).
+ * 3. If a function needs protection, regardless of the CSR_WIFI_SINGLE_FUNCTION
+ *    then we call directly the sdio_claim_host/sdio_release_host().
+ *    Use of this must be restricted to the SDIO glue layer only (e.g. sdio_mmc.c).
+ *
+ * Note: The _func and function pointers are _not_ the same.
+ * The former is the (struct sdio_func*) context, which restricts the use to the SDIO glue layer.

+* Texas Instrument OMAP SCM bandgap bindings
+
+In the System Control Module, OMAP supplies a voltage reference
+and a temperature sensor feature that are gathered in the band
+gap voltage and temperature sensor (VBGAPTS) module. The band
+gap provides current and voltage reference for its internal
+circuits and other analog IP blocks. The analog-to-digital
+converter (ADC) produces an output value that is proportional
+to the silicon temperature.
+
+Required properties:
+- compatible : Should be:
+  - "ti,omap4460-control-bandgap" : for OMAP4460 bandgap
+  - "ti,omap5430-control-bandgap" : for OMAP5430 bandgap
+- interrupts : this entry should indicate which interrupt line
+the talert signal is routed to;
+Specific:
+- ti,tshut-gpio : this entry should be used to inform which GPIO
+line the tshut signal is routed to;
+
+Example:
+
+bandgap {
+	reg = <0x4a002260 0x4
+		0x4a00232C 0x4
+		0x4a002378 0x18>;
+	compatible = "ti,omap4460-control-bandgap";
+	interrupts = <0 126 4>; /* talert */
+	ti,tshut-gpio = <86>;
+};

 TODO:
-	- review user mode interface and determine if ioctls can be replaced

-	  if ioctls are still required and allocate ioctl numbers from
-	  ioctl-number.txt.
+	- Convert event tracing code to in-kernel tracing infrastructure

+	- Convert debug prints to appropriate dev_debug or something better
+	- Modify Kconfig to add CONFIG option for enabling/disabling event

 	- check USB HCD implementation is complete and correct.
-	- remove any debug and trace code.
 	- code review by USB developer community.
 	- testing with as many devices as possible.

+ * This allocator is designed for use with zcache and zram. Thus, the
+ * allocator is supposed to work well under low memory conditions. In
+ * particular, it never attempts higher order page allocation which is
+ * very likely to fail under memory pressure. On the other hand, if we
+ * just use single (0-order) pages, it would suffer from very high
+ * fragmentation -- any object of size PAGE_SIZE/2 or larger would occupy
+ * an entire page. This was one of the major issues with its predecessor
+ * (xvmalloc).
+ *
+ * To overcome these issues, zsmalloc allocates a bunch of 0-order pages
+ * and links them together using various 'struct page' fields. These linked
+ * pages act as a single higher-order page i.e. an object can span 0-order
+ * page boundaries. The code refers to these linked pages as a single entity
+ * called zspage.
+ *
+ * Following is how we use various fields and flags of underlying
+ * struct page(s) to form a zspage.
+ *
+ * Usage of struct page fields:
+ *	page->first_page: points to the first component (0-order) page
+ *	page->index (union with page->freelist): offset of the first object
+ *		starting in this page. For the first page, this is
+ *		always 0, so we use this field (aka freelist) to point
+ *		to the first free object in zspage.
+ *	page->lru: links together all component pages (except the first page)
+ *		of a zspage
+ *
+ *	For _first_ page only:
+ *
+ *	page->private (union with page->first_page): refers to the
+ *		component page after the first page
+ *	page->freelist: points to the first free object in zspage.
+ *		Free objects are linked together using in-place
+ *		metadata.
+ *	page->objects: maximum number of objects we can store in this
+ *		zspage (class->zspage_order * PAGE_SIZE / class->size)
+ *	page->lru: links together first pages of various zspages.
+ *		Basically forming list of zspages in a fullness group.
+ *	page->mapping: class index and fullness group of the zspage
+ *
+ * Usage of struct page flags:
+ *	PG_private: identifies the first component page
+ *	PG_private2: identifies the last component page

-/* List of quirky USB devices.  Please keep this list ordered by:
+/* Lists of quirky USB devices, split in device quirks and interface quirks.
+ * Device quirks are applied at the very beginning of the enumeration process,
+ * right after reading the device descriptor. They can thus only match on device
+ * information.
+ *
+ * Interface quirks are applied after reading all the configuration descriptors.
+ * They can match on both device and interface information.
+ *
+ * Note that the DELAY_INIT and HONOR_BNUMINTERFACES quirks do not make sense as
+ * interface quirks, as they only influence the enumeration process which is run
+ * before processing the interface quirks.
+ *
+ * Please keep the lists ordered by:
  * 	1) Vendor ID
  * 	2) Product ID
  * 	3) Class ID
- *
- * as we want specific devices to be overridden first, and only after that, any
- * class specific quirks.
- *
- * Right now the logic aborts if it finds a valid device in the table, we might
- * want to change that in the future if it turns out that a whole class of
- * devices is broken...
