The Keystone II devices have a set of registers that are used to control
the status of its peripherals. This node is intended to allow access to
this functionality.

On ARM Chromebooks we have a few devices that are accessed by both the
AP (the main "Application Processor") and the EC (the Embedded
Controller). These are:
* The battery (sbs-battery).
* The power management unit tps65090.
On the original Samsung ARM Chromebook these devices were on an I2C
bus that was shared between the AP and the EC and arbitrated using
some extranal GPIOs (see i2c-arb-gpio-challenge).
The original arbitration scheme worked well enough but had some
downsides:
* It was nonstandard (not using standard I2C multimaster)
* It only worked if the EC-AP communication was I2C
* It was relatively hard to debug problems (hard to tell if i2c issues
were caused by the EC, the AP, or some device on the bus).
On the HP Chromebook 11 the design was changed to:
* The AP/EC comms were still i2c, but the battery/tps65090 were no
longer on the bus used for AP/EC communication. The battery was
exposed to the AP through a limited i2c tunnel and tps65090 was
exposed to the AP through a custom Linux driver.
On the Samsung ARM Chromebook 2 the scheme is changed yet again, now:
* The AP/EC comms are now using SPI for faster speeds.
* The EC's i2c bus is exposed to the AP through a full i2c tunnel.
The upstream "tegra124-venice2" uses the same scheme as the Samsung
ARM Chromebook 2, though it has a different set of components on the
other side of the bus.
This driver supports the scheme used by the Samsung ARM Chromebook 2.
Future patches to this driver could add support for the battery tunnel
on the HP Chromebook 11 (and perhaps could even be used to access
tps65090 on the HP Chromebook 11 instead of using a special driver,
but I haven't researched that enough).

In certain boards the source for the clk32k clock can be gated. In these
boards the clk32k clock can be provided to the driver and it is going to be
enabled/disabled when it is needed.
If the clk32k clock is not provided the driver will assume that it is always
running.

SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.
This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.
The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.
After discussion at last year's KS (and some more on the mailing lists),
we are here adding a drivers/soc directory. The purpose of this is
to keep per-vendor shared code that's needed by different drivers but
that doesn't fit into the MFD (nor drivers/platform) model. We expect
to keep merging contents for this hierarchy through arm-soc so we can
keep an eye on what the vendors keep adding here and not making it a
free-for-all to shove in crazy stuff.

The bulk of this branch is updates for Renesas Shmobile. They are still
doing some enablement for classic boards first, and then come up with DT
bindings when they've had a chance to learn more about the hardware. Not
necessarily a bad way to go about it, and they're looking at moving some
of the temporary board code resulting from it to drivers/staging instead
to avoid the churn here.
As a result of the shmobile clock cleanups, we end up merging quite a
bit of SH code here as well. We ended up merging it here instead of in
the cleanup branch due to the other board changes depending on it.

Pull block core updates from Jens Axboe:
"It's a big(ish) round this time, lots of development effort has gone
into blk-mq in the last 3 months. Generally we're heading to where
3.16 will be a feature complete and performant blk-mq. scsi-mq is
progressing nicely and will hopefully be in 3.17. A nvme port is in
progress, and the Micron pci-e flash driver, mtip32xx, is converted
and will be sent in with the driver pull request for 3.16.
This pull request contains:
- Lots of prep and support patches for scsi-mq have been integrated.
All from Christoph.
- API and code cleanups for blk-mq from Christoph.
- Lots of good corner case and error handling cleanup fixes for
blk-mq from Ming Lei.
- A flew of blk-mq updates from me:
* Provide strict mappings so that the driver can rely on the CPU
to queue mapping. This enables optimizations in the driver.
* Provided a bitmap tagging instead of percpu_ida, which never
really worked well for blk-mq. percpu_ida relies on the fact
that we have a lot more tags available than we really need, it
fails miserably for cases where we exhaust (or are close to
exhausting) the tag space.
* Provide sane support for shared tag maps, as utilized by scsi-mq
* Various fixes for IO timeouts.
* API cleanups, and lots of perf tweaks and optimizations.
- Remove 'buffer' from struct request. This is ancient code, from
when requests were always virtually mapped. Kill it, to reclaim
some space in struct request. From me.
- Remove 'magic' from blk_plug. Since we store these on the stack
and since we've never caught any actual bugs with this, lets just
get rid of it. From me.
- Only call part_in_flight() once for IO completion, as includes two
atomic reads. Hopefully we'll get a better implementation soon, as
the part IO stats are now one of the more expensive parts of doing
IO on blk-mq. From me.
- File migration of block code from {mm,fs}/ to block/. This
includes bio.c, bio-integrity.c, bounce.c, and ioprio.c. From me,
from a discussion on lkml.
That should describe the meat of the pull request. Also has various
little fixes and cleanups from Dave Jones, Shaohua Li, Duan Jiong,
Fengguang Wu, Fabian Frederick, Randy Dunlap, Robert Elliott, and Sam
Bradshaw"

- We are finalizing and fixing up the gpiochip irqchip helpers
bringing a helpful irqchip implementation into the gpiolib
core and avoiding duplicate code and, more importantly,
duplicate bug fixes:
- Support for using the helpers with threaded interrupt
handlers as used on sleeping GPIO-irqchips
- Do not set up hardware triggers for edges or levels if
the default IRQ type is IRQ_TYPE_NONE - some drivers
would exploit the fact that you could get default
initialization of the IRQ type from the core at probe()
but if no default type is set up from the helper, we
should not call the driver to configure anything. Wait
until a consumer requests the interrupt instead.
- Make the irqchip helpers put the GPIO irqs into their
own lock class. The GPIO irqchips can often emit
(harmless, but annoying) lockdep warnings about recursions
when they are in fact just cascaded IRQs. By putting
them into their own lock class we help the lockdep core
to keep track of things.
- Switch the tc3589x GPIO expanders to use the irqchip
helpers
- Switch the OMAP GPIO driver to use the irqchip helpers
- Add some documentation for the irqchip helpers
- select IRQ_DOMAIN when using the helpers since some
platforms may not be using this by default and it's a
strict dependency.
- Continued GPIO descriptor refactoring:
- Remove the one instance of gpio_to_desc() from the
device tree code, making the OF GPIO code use GPIO
descriptors only.
- Introduce gpiod_get_optional() and
gpiod_get_optional_index() akin to the similar
regulator functions for cases where the use of GPIO
is optional and not strictly required.
- Make of_get_named_gpiod_flags() private - we do not
want to unnecessarily expose APIs to drivers that
make the gpiolib harder than necessary to maintain
and refactor. Privatize this function.
- Support "-gpio" suffix for the OF GPIO retrieveal path.
We used to look for "foo-gpios" or just "gpios" in device
tree nodes, but it turns out that some drivers with a
single GPIO line will just state "foo-gpio" (singularis).
Sigh. Support this with a fallback looking for it, as
this simplifies driver code and handles it in core code.
- Switch the ACPI GPIO core to fetch GPIOs with the
*_cansleep function variants as the GPIO operation
region handler can sleep, and shall be able to handle
gpiochips that sleep.
- Tons of cleanups and janitorial work from Jingoo Han,
Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe.
Notably Jingoo cut off a ton of pointless OOM messages.
- Incremental development and fixes for various drivers,
nothing really special here.

"This is the bulk of GPIO changes for the v3.16 series.

well.

Exynos drm hdmi driver used to get dummy hdmiphy clock to
control the PMU bit for hdmiphy. This bit needs to be set
before setting any resolution to hdmi hardware. This was
handled using dummy hdmiphy clock which is removed here.
PMU is already defined as system controller for exynos
SoCs. Hdmi driver is modified to control the phy enable bit
inside PMU using regmap interfaces.
Devicetree binding document for hdmi is also updated.

Certain bridge chips use a GPIO to indicate the cable status instead
of the I_DP_HPD pin. This adds an optional device-tree property,
"samsung,hpd-gpio", to the exynos-dp controller which indicates that
the specified GPIO should be used for hotplug detection.
The GPIO is then set up as an edge-triggered interrupt where the
rising edge indicates hotplug-in and the falling edge indicates hotplug-out.

when installing the following table during early stage:
ACPI: SSDT 0x00000000B9638018 07A0C4 (v02 INTEL S2600CP 00004000 INTL 20100331)
The regression is caused by the size limitation of the x86 early IO mapping.
The root cause is:
1. ACPICA doesn't split IO memory mapping and table mapping;
2. Linux x86 OSL implements acpi_os_map_memory() using a size limited fix-map
mechanism during early boot stage, which is more suitable for only IO
mappings.
This patch fixes this issue by utilizing acpi_gbl_verify_table_checksum to
disable the table mapping during early stage and enabling it again for the
late stage. In this way, the normal code path is not affected. Then after
the code related to the root cause is cleaned up, the early checksum
verification can be easily re-enabled.
A new boot parameter - acpi_force_table_verification is introduced for
the platforms that require the checksum verification to stop loading bad
tables.
This fix also covers the checksum verification for the table overrides. Now
large tables can also be overridden using the initrd override mechanism.

John W. Linville says:
====================
Please pull this batch of updates intended for 3.16...
For the mac80211 bits, Johannes says:
"Here I just have Heikki's rfkill GPIO cleanups.
The ARM/tegra patch is OK with the maintainer (Stephen). Let me know of
any problems."
and;
"We have a whole bunch of work on CSA by Andrei, Luca and Michal, but
unfortunately it doesn't seem quite complete yet so it's still disabled.
There's some TDLS work from Arik, and the rest is mostly minor fixes and
cleanups."
For the NFC bits, Samuel says:
"This is the NFC pull request for 3.16. We have:
- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
thus relies on the HCI stack. This submission provides support for tag
redaer/writer mode (including Type 5) and device tree bindings.
- PM runtime support and a bunch of bug fixes for TI's trf7970a.
- Device tree support for NXP's pn544. Legacy platform data support is
obviously kept intact.
- NFC Tag type 4B support to the NFC Digital stack.
- SOCK_RAW type support to the raw NFC socket, and allow NCI
sniffing from that. This can be extended to report HCI frames and also
proprietarry ones like e.g. the pn533 ones."
For the iwlwifi bits, Emmanuel says:
"Eran continues to work on new devices, Eyal is still digging in
the rate control stuff, and Johannes added new functionality to the
debug system we have in place now along with a few cleanups he made
on the way. That's pretty much it."
and;
"Avri continues to work on the power code and Eran is improving the
NVM handling as a preparations for new devices on which he works
with Liad. Luca cleans up a bit the code while working on CSA. I have
the regular BT Coex stuff and a small lockdep fix. Johannes has his
regular amount of clean ups and improvements, the main one is the
ability to leave 2 chains open to improve diversity and hence the
throughput in high attenuation scenarios."
and;
"The regular amount of housekeeping here. I merged iwlwifi-fixes.git to
be able to add the patch you didn't want in wireless.git at that stage
of the -rc cycle. Luca has a few preparations for CSA implementation
and also what seems to be a bugfix for P2P but hasn't caused issues
we could notice."
For the Atheros bits, Kalle says:
"For ath10k Michal did various small fixes on how we handle
hardware/firmware problems and he also fixed two memory leaks."
Also included are a couple of pulls from the wireless tree to
avoid/resolve merge issues...

I'm not sure why a client would want to stuff multiple reads in a
single compound rpc, but it's legal for them to do it, and we should
really support it.

because dm-cache cannot yet handle discards that span cache blocks.
Really fix a dm-mpath LOCKDEP warning that was introduced in -rc1.
Add a 'no_space_timeout' control to dm-thinp to restore the ability to
queue IO indefinitely when no data space is available. This fixes a
change in behavior that was introduced in -rc6 where the timeout
couldn't be disabled.

Add support for a generic PCI host controller, such as a
firmware-initialised device with static windows or an emulation by
something such as kvmtool.
The controller itself has no configuration registers and has its address
spaces described entirely by the device-tree (using the bindings from
ePAPR). Both CAM and ECAM are supported for Config Space accesses.
Add corresponding documentation for the DT binding.
