* ASoC: core: Add initial support for DAI multicodecBenoit Cousson2014-07-163-90/+220
| | | | | | | | | | | | | | | | | | | | | | | | | | DAI link assumes a one to one mapping between CPU DAI and CODEC. In some cases, the same CPU DAI can be connected to several codecs. This is the case for example, if you connect two mono codecs to the same I2S link in order to have a stereo card. The current ASoC implementation does not allow such setup. Add support for DAI links composed of a single CPU DAI and multiple CODECs. Sound cards have to pass the CODECs array in the corresponding DAI link through a new 'snd_soc_dai_link_component' struct. Each CODEC in this array is described in the same manner single CODEC DAIs are (either DT/OF node or codec_name). Multi-codec links are not supported in the case of CODEC to CODEC links. Just print a warning if it happens. Based on an original code done by Misael.

| * ASoC: core: Move non-shared code paths out of snd_soc_post_component_init()Lars-Peter Clausen2014-07-021-75/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two call sites for snd_soc_post_component_init(), one passes 0 and the other 1 for the 'dailess' parameter of snd_soc_post_component_init(). Depending on whether 'dailess' is 0 or 1 snd_soc_post_component_init() runs different code at the beginning and the end of the function. The patch moves this conditional code out of snd_soc_post_component_init() and into the call sites. This removes the need for snd_soc_post_component_init() to know whether it is called for a DAI link or a aux dev. Also do the initialization of rtd->card when the rtd struct is allocated.

| * ASoC: core: Bind aux devs earlyLars-Peter Clausen2014-07-021-42/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently in snd_soc_instantiate_card() we only check if the aux dev exists, but do not yet assign it to its rtd. This means that we need to lookup the aux dev again in soc_probe_aux_dev(). This patch changes the behavior to assign the aux dev to the rtd in soc_check_aux_dev() (and renames it to soc_bind_aux_dev()). This simplifies the implementation a bit and also removes the need for soc_post_component_init() to know about the specific CODEC that was assigned to the rtd. The later is necessary for componentization as the code should work for all types of components not just CODECs. This new behavior is also more in sync with how soc_bind_dai_link()/soc_probe_link_dais() works. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

This is meant to unify the handling of these callbacks across different types of components and will eventually allow their removal from the CODEC and platfrom driver structs. The new callbacks are slightly different from the old ones in that they take a snd_soc_component as a parameter rather than a snd_soc_dapm_context. This was done since otherwise casting from the DAPM context to the component would typically be the first thing to do in the callback. And the interface becomes slightly cleaner by passing a snd_soc_component to all callbacks in the snd_soc_component_driver struct. The patch also already removes the stream_event() callback from the snd_soc_codec_driver and snd_soc_platform_driver structs as it is currently unused.

| * | ASoC: Add DAPM support at the component levelLars-Peter Clausen2014-06-214-41/+110

Previously there was only full DAPM support for CODECs and partial DAPM support (e.g. no Mixers nor MUXs) for platforms. Having DAPM support at the component level will allow all types of components to use DAPM and also help in consolidating the DAPM support between CODECs and platforms. Since the DAPM context is directly embedded into the snd_soc_codec and snd_soc_platform struct and the 'dapm' field is directly referenced in a lot of drivers moving the field just right now is not possible without causing code churn. The approach this patch takes is to add two new fields to the component struct. One field which is the pointer to the actual DAPM context used by the component and one DAPM context that will be used as the default if no other context was specified. For CODECs and platforms the pointer is initialized to point to the CODEC or platform DAPM context. All generic code when referencing a component's DAPM struct will go via the pointer. This will make it possible to eventually seamlessly move the DAPM context from snd_soc_codec and snd_soc_platform struct over once all direct references have been eliminated.

| * | ASoC: Add a set_bias_level() callback to the DAPM context structLars-Peter Clausen2014-06-213-8/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the DAPM code directly looks at the CODEC driver struct to get a handle to the set_bias_level() callback. This patch adds a new set_bias_level() callback to the DAPM context struct. The DAPM code will use this new callback instead of the CODEC callback. For CODECs the new callback is set up to call the CODEC specific set_bias_level callback(). Not looking directly at the CODEC driver struct will allow non CODEC DAPM contexts to implement a set_bias_level() callback. This is also similar to how the seq_notifier() and stream_event() callbacks are currently handled. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

Fix this by doing snd_soc_test_bits() unconditionally as it was before but by using separate flags for kcontrol and register state changes. This allow both DAPM graph to be updated when disabling auto-muted control and update register if it is out-of-sync in respect of kcontrol state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently only pins in CODEC DAPM contexts are automatically marked as non-connected if the card has the fully_routed flag set. This makes sense since widgets which qualify for auto-disconnection are only found in CODEC DAPM contexts. But with componentisation this is going to change, so consider all widgets for auto-disconnection. Also it is probably faster to walk the widgets list only once rather than once for each CODEC.

Using a 2-stage registration approach has the advantage that it is possible to modify the component after it has been initialized, but before it is made visible to the system. This e.g. allows CODECs or platforms to overwrite some of the default settings made in snd_soc_component_initialize(). Similar snd_soc_component_unregister() is split into two steps as well, snd_soc_component_delete(), which removes the component from the system, and snd_soc_component_cleanup(), which frees all the resources allocated by the component. Furthermore this patch makes sure that if a component is visible on two list (e.g. the component list and the CODEC list) it is added or removed to both lists atomically.

The purpose of this was to discourage users from tweaking rto_alpha and rto_beta knobs in production environments since they are key to correctly compute rtt/srtt. RFC4960 under section 6.3.1. RTO Calculation says regarding rto_alpha and rto_beta under rule C3 and C4: [...] C3) When a new RTT measurement R' is made, set RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'| and SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R' Note: The value of SRTT used in the update to RTTVAR is its value before updating SRTT itself using the second assignment. After the computation, update RTO <- SRTT + 4 * RTTVAR. C4) When data is in flight and when allowed by rule C5 below, a new RTT measurement MUST be made each round trip. Furthermore, new RTT measurements SHOULD be made no more than once per round trip for a given destination transport address. There are two reasons for this recommendation: First, it appears that measuring more frequently often does not in practice yield any significant benefit [ALLMAN99]; second, if measurements are made more often, then the values of RTO.Alpha and RTO.Beta in rule C3 above should be adjusted so that SRTT and RTTVAR still adjust to changes at roughly the same rate (in terms of how many round trips it takes them to reflect new values) as they would if making only one measurement per round-trip and using RTO.Alpha and RTO.Beta as given in rule C3. However, the exact nature of these adjustments remains a research issue. [...] While it is discouraged to adjust rto_alpha and rto_beta and not further specified how to adjust them, the RFC also doesn't explicitly forbid it, but rather gives a RECOMMENDED default value (rto_alpha=3, rto_beta=2). We have a couple of users relying on the old permissions before they got changed. That said, if someone really has the urge to adjust them, we could allow it with a warning in the log.

The logic introduced in commit 7e3cead5172927732f51fde ("net: Save software checksum complete") is not correct. This patch: 1) Restores code in __skb_checksum_complete_header except for setting CHECKSUM_UNNECESSARY. This function may be calculating checksum on something less than skb->len. 2) Adds saving checksum to __skb_checksum_complete. The full packet checksum 0..skb->len is calculated without adding in pseudo header. This value is saved in skb->csum and then the pseudo header is added to that to derive the checksum for validation. 3) In both __skb_checksum_complete_header and __skb_checksum_complete, set skb->csum_valid to whether checksum of zero was computed. This allows skb_csum_unnecessary to return true without changing to CHECKSUM_UNNECESSARY which was done previously. 4) Copy new csum related bits in __copy_skb_header.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Its too easy to add thousand of UDP sockets on a particular bucket, and slow down an innocent multicast receiver. Early demux is supposed to be an optimization, we should avoid spending too much time in it. It is interesting to note __udp4_lib_demux_lookup() only tries to match first socket in the chain. 10 is the threshold we already have in __udp4_lib_lookup() to switch to secondary hash.

| * | vxlan: use dev->needed_headroom instead of dev->hard_header_lenCong Wang2014-06-131-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we mirror packets from a vxlan tunnel to other device, the mirror device should see the same packets (that is, without outer header). Because vxlan tunnel sets dev->hard_header_len, tcf_mirred() resets mac header back to outer mac, the mirror device actually sees packets with outer headers Vxlan tunnel should set dev->needed_headroom instead of dev->hard_header_len, like what other ip tunnels do. This fixes the above problem. Cc: "David S.

Original tag message: Allwinner sunXi SoCs clock changes This pull contains some new code to add support for A31 clocks by Maxime and Boris. It also reworks the driver a bit to avoid having a huge single file when we have a full folder for ourselves, and separating different functional units makes sense.
