This is based on the work of Teddy Reed <teddy@prosauce.org> published
on GitHub:
https://github.com/theopolis/tpm-i2c-atmel.git
34894b988b67e0ae55088d6388e77b0dbf10c07d
That driver was never merged, I have taken it as a starting port,
forward ported, tested and revised the driver:
- Make it broadly textually similar to the Infineon and Nuvoton I2C
driver
- Place everything in a format suitable for mainline inclusion
- Use high level I2C functions i2c_master_send and
i2c_master_recv for data xfer
- Use the timeout system from the core code, by faking out a status
register
- Only I2C transfer the number of bytes in the reply, not a fixed
message size.
- checkpatch cleanups
- Testing on ARM Kirkwood, with this device tree, using a
AT97SC3204T-X1A180
tpm@29 {
compatible = "atmel,at97sc3204t";
reg = <0x29>;

This chip is/was also branded as a Winbond WPCT301.
Originally written by Dan Morav <dmorav@nuvoton.com> and posted to LKML:
https://lkml.org/lkml/2011/9/7/206
The original posting was not merged, I have taken it as a
starting point, forward ported, tested and revised the driver:
- Rework interrupt handling to work properly with level triggered
interrupts. The old version just locked up.
- Synchronize various items with Peter Huewe's Infineon driver:
* Add durations/timeouts sysfs calls
* Remove I2C device auto-detection
* Don't fiddle with chip->release
* Call tpm_dev_vendor_release in the probe error path
* Use MODULE_DEVICE_TABLE for the I2C ids
* Provide OF compatible strings for DT support
* Use SIMPLE_DEV_PM_OPS
* Use module_i2c_driver
- checkpatch cleanups
- Testing on ARM Kirkwood with GPIO interrupts, with this device tree:
tpm@57 {
compatible = "nuvoton,npct501";
reg = <0x57>;
interrupt-parent = <&gpio1>;
interrupts = <6 IRQ_TYPE_LEVEL_LOW>;
};

Add a generic associative array implementation that can be used as the
container for keyrings, thereby massively increasing the capacity available
whilst also speeding up searching in keyrings that contain a lot of keys.
This may also be useful in FS-Cache for tracking cookies.
Documentation is added into Documentation/associative_array.txt
Some of the properties of the implementation are:
(1) Objects are opaque pointers. The implementation does not care where they
point (if anywhere) or what they point to (if anything).
[!] NOTE: Pointers to objects _must_ be zero in the two least significant
bits.
(2) Objects do not need to contain linkage blocks for use by the array. This
permits an object to be located in multiple arrays simultaneously.
Rather, the array is made up of metadata blocks that point to objects.
(3) Objects are labelled as being one of two types (the type is a bool value).
This information is stored in the array, but has no consequence to the
array itself or its algorithms.
(4) Objects require index keys to locate them within the array.
(5) Index keys must be unique. Inserting an object with the same key as one
already in the array will replace the old object.
(6) Index keys can be of any length and can be of different lengths.
(7) Index keys should encode the length early on, before any variation due to
length is seen.
(8) Index keys can include a hash to scatter objects throughout the array.
(9) The array can iterated over. The objects will not necessarily come out in
key order.
(10) The array can be iterated whilst it is being modified, provided the RCU
readlock is being held by the iterator. Note, however, under these
circumstances, some objects may be seen more than once. If this is a
problem, the iterator should lock against modification. Objects will not
be missed, however, unless deleted.
(11) Objects in the array can be looked up by means of their index key.
(12) Objects can be looked up whilst the array is being modified, provided the
RCU readlock is being held by the thread doing the look up.
The implementation uses a tree of 16-pointer nodes internally that are indexed
on each level by nibbles from the index key. To improve memory efficiency,
shortcuts can be emplaced to skip over what would otherwise be a series of
single-occupancy nodes. Further, nodes pack leaf object pointers into spare
space in the node rather than making an extra branch until as such time an
object needs to be added to a full node.

Commit d50240a5f6ce ("arm64: mm: permit use of tagged pointers at EL0")
added support for tagged pointers in userspace, but the corresponding
update to Documentation/ contained some imprecise statements.
This patch fixes up some minor ambiguities in the text, hopefully making
it more clear about exactly what the kernel expects from user virtual
addresses.

Pull networking fixes from David Miller:
1) If the local_df boolean is set on an SKB we have to allocate a
unique ID even if IP_DF is set in the ipv4 headers, from Ansis
Atteka.
2) Some fixups for the new chipset support that went into the sfc
driver, from Ben Hutchings.
3) Because SCTP bypasses a good chunk of, and actually duplicates, the
logic of the ipv6 output path, some IPSEC things don't get done
properly. Integrate SCTP better into the ipv6 output path so that
these problems are fixed and such issues don't get missed in the
future either. From Daniel Borkmann.
4) Fix skge regressions added by the DMA mapping error return checking
added in v3.10, from Mikulas Patocka.
5) Kill some more IRQF_DISABLED references, from Michael Opdenacker.
6) Fix races and deadlocks in the bridging code, from Hong Zhiguo.

resources. From Jason Wang.
8) Prevent format-string injection into xen-netback driver, from Kees
Cook.
9) Fix regression added to netpoll ARP packet handling, in particular
check for the right ETH_P_ARP protocol code. From Sonic Zhang.
10) Try to deal with AMD IOMMU errors when using r8169 chips, from
Francois Romieu.
11) Cure freezes due to recent changes in the rt2x00 wireless driver,
from Stanislaw Gruszka.
12) Don't do SPI transfers (which can sleep) in interrupt context in
cw1200 driver, from Solomon Peachy.
13) Fix LEDs handling bug in 5720 tg3 chips already handled for 5719.
From Nithin Sujir.
14) Make xen_netbk_count_skb_slots() count the actual number of slots
that will be used, taking into consideration packing and other
issues that the transmit path will run into. From David Vrabel.
15) Use the correct maximum age when calculating the bridge
message_age_timer, from Chris Healy.
16) Get rid of memory leaks in mcs7780 IRDA driver, from Alexey
Khoroshilov.
17) Netfilter conntrack extensions were converted to RCU but are not
always freed properly using kfree_rcu(). Fix from Michal Kubecek.
18) VF reset recovery not being done correctly in qlcnic driver, from
Manish Chopra.

We're still working out how this should be handled for RAW and UDP
sockets. From Daniel Borkmann and Duan Jiong.
24) We've had several bugs wherein the network namespace's loopback
device gets accessed after it is free'd, NULL it out so that we can
catch these problems more readily. From Eric W Biederman.
25) Fix regression in TCP RTO calculations, from Neal Cardwell.
26) Fix too early free of xen-netback network device when VIFs still

running bonding in ALB mode requires that learning packets be sent periodically,
so that the switch knows where to send responding traffic. However, depending
on switch configuration, there may not be any need to send traffic at the
default rate of 3 packets per second, which represents little more than wasted
data. Allow the ALB learning packet interval to be made configurable via sysfs

This commit fixes the DT binding for the Armada 370/XP SoC timer.
The previous "marvell,armada-370-xp-timer" compatible is removed and
two new compatible strings are introduced: "marvell,armada-xp-timer"
and "marvell,armada-370-timer".
The rationale behind this change is that the Armada 370 SoC and the
Armada XP SoC timers are not really compatible:
* Armada 370 has no 25 MHz fixed timer.
* Armada XP cannot work properly without such 25 MHz fixed timer
as doing otherwise leads to using a clocksource whose frequency
varies when doing cpufreq frequency changes.
This commit also removes the "marvell,timer-25Mhz" property, given
it's now meaningless.

The Ralink RT3883 SoCs have a built-in PCI Host Controller
device. The patch adds a platform driver and device tree
binding documentation for that.
The patch also enables the HW_HAS_PCI config option. This
is required in order to be able to enable the PCI support.

For a long time no filesystem has been using vfs_follow_link, and as seen
by recent filesystem submissions any new use is accidental as well.
Remove vfs_follow_link, document the replacement in
Documentation/filesystems/porting and also rename __vfs_follow_link
to match its only caller better.

Add hardware blinking support to the pca9633 driver.
NOTE: Hardware blinking violates the leds infrastructure
driver interface since the hardware only supports
blinking all LEDs with the same delay_on/delay_off
rates. That is, only the LEDs that are set to blink
will actually blink but all LEDs that are set to blink
will blink in identical fashion. The delay_on/delay_off
values of the last LED that is set to blink will be used
for all of the blinking LEDs. If the hardware doesn't
support the requested blinking pattern, a default of
500ms on and off will be used.
Hardware blinking is disabled by default but can be enabled
by setting the 'blink_type' member in the platform_data
struct to 'PCA9633_HW_BLINK' or by adding the 'nxp,hw-blink'
property to the DTS.

LP8501 can drive up to 9 channels like LP5523.
LEDs can be controlled directly via the I2C and programmable engines are
supported.
LP55xx common driver
LP8501 is one of LP55xx family device, so LP55xx common code are used.
Chip specific data is defined in the structure, 'lp55xx_device_config'.
Differences between LP8501 and LP5523
Different register layout for LED output control and others.
LP8501 specific feature for separate output power selection.
LP8501 doesn't support external clock detection.
Different programming engine data.
LP8501 specific feature - output power selection
Output channels are selected by power selection - Vout or Vdd.
Separate power for VDD1-6 and VDD7-9 are available.
It is configurable in the platform data.
To support this feature, LP55xx DT structure and header are changed.
Device tree binding is updated as well.
LED pattern data
Example pattern data is updated in the driver documentation.

The compatible string of the kirkwood-i2s driver was chosen as
"marvell,mvebu-audio". Using such a compatible string is not a good
idea, since "mvebu" is the name of a large family of SOCs, in which
new, unknown SOCs will be coming in the future. It is therefore
impossible to know what will be evolutions of this hardware block in
the next generations of the SOCs. For this reason, the recommandation
for compatible strings of on-SOCs devices has always been to use the
name of the oldest SOC that has the hardware block. New SOCs that have
an exactly compatible hardware block can reference it using the same
compatible string. See [1], [2] and [3] for various cases were this
suggestion was made, including from Rob Herring, a Device Tree binding
maintainer.
As an example, there are already small differences between current
generations:
* On Kirkwood, only one interrupt is used for audio.
* On Dove, two interrupts are used, one for audio data and one for
error reporting.
In the near future, I'll be adding audio support to Armada 370, which
allows has the same hardware block (but maybe with minor variants).
Therefore, this patch changes the driver to accept
"marvell,kirkwood-audio" and "marvell,dove-audio" as compatible
strings instead of the too-generic "marvell,mvebu-audio". The reason
for the two different compatible strings is the difference in the
number of interrupts used by the two SOCs for audio.
This Device Tree binding has never been part of a Linux kernel stable
release so far, so it can be changed now without breaking backward
compatibility.

The biggest change is about exynos thermal driver restructure. The
patch set adds TMU (Thermal management Unit) driver support for
exynos5440 platform. There are 3 instances of the TMU controllers so
necessary cleanup/re-structure is done to handle multiple thermal
zone.
The next biggest change is the introduction of the imx thermal driver.
It adds the imx thermal support using Temperature Monitor (TEMPMON)
block found on some Freescale i.MX SoCs. The driver uses syscon
regmap interface to access TEMPMON control registers and calibration
data, and supports cpufreq as the cooling device.
Highlights:
- restructure exynos thermal driver.
- introduce new imx thermal driver.
- fix a bug in thermal core, which powers on the fans unexpectedly
after resume from suspend"

When registering a thermal zone device using platform information
via bind_params, the thermal framework will always perform the
cdev binding using the lowest and highest limits (THERMAL_NO_LIMIT).
This patch changes the data structures so that it is possible
to inform what are the desired limits for each trip point
inside a bind_param. The way the binding is performed is also
changed so that it uses the new data structure.

When registering a new thermal_device, the thermal framework
will always add a hwmon sysfs interface.
This patch adds a flag to make this behavior optional. Now
when registering a new thermal device, the caller can
optionally inform if hwmon interface is desirable. This can
be done by means of passing a thermal_zone_params.no_hwmon == true.
In order to keep same behavior as of today, all current
calls will by default create the hwmon interface.

This is based on the initial imx thermal work done by
Rob Lee <rob.lee@linaro.org> (Not sure if the email address is still
valid). Since he is no longer interested in the work and I have
rewritten a significant amount of the code, I just took the authorship
over from him.
It adds the imx thermal support using Temperature Monitor (TEMPMON)
block found on some Freescale i.MX SoCs. The driver uses syscon regmap
interface to access TEMPMON control registers and calibration data, and

Currently, we have a number of documentation files that live under
fs/cifs/. Generally, these don't get picked up by distro packagers,
since they're in a non-standard location. Move them to a new spot
under Documentation/ instead.
