ad2109d7d2 ASoC: Updates for v3.10
A bunch of changes here, the most interesting one subsystem wise being
 Morimoto-san's work to create snd_soc_component which doesn't do much
 for now but will be pretty important going forwards:
 
  - Add a new component object type which will form the basis of moving
    to a more generic handling of SoC and off-SoC components, contributed
    by Kuninori Morimoto.
  - A fairly large set of cleanups for the dmaengine integration from
    Lars-Peter Clausen, starting to move towards being able to have a
    generic driver based on the library.
  - Performance optimisations to DAPM from Ryo Tsutsui.
  - Support for mixer control sharing in DAPM from Stephen Warren.
  - Multiplatform ARM cleanups from Arnd Bergmann.
  - New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.

e6a9081055 Input: st1232 - add reset pin handling
We add the possibility to hand over a GPIO number for the reset pin.
This way we can remove existing board code that takes care of it and
group this information properly in the platform data or in the device
tree configuration.

After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching
by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to
just MATCH_SUBDEV.
The v4l2-dbg utility is much better placed to match by name by just enumerating
all bridge and subdev devices until chip_name.name matches.

i2c programmable clock generators. Currently, the driver does not
support VXCO feature of si5351b. Passing platform_data or DT bindings
selectively allows to overwrite stored Si5351 configuration which is

c61c86dd6e tpm: Add support for new Infineon I2C TPM (SLB 9645 TT 1.2 I2C)
This driver adds support for Infineon's new SLB 9645 TT 1.2 I2C TPMs,
which supports clockstretching, combined reads and a bus speed of
up to 400khz. The device also has a new device id.

The driver works now also fine with device trees, so you can
instantiate your device by adding:
 +       tpm {
 +               compatible = "infineon,slb9645tt";
 +               reg = <0x20>;
 +       };
 for SLB 9645 devices or

 +       tpm {
 +               compatible = "infineon,slb9635tt";
 +               reg = <0x20>;
 +       };
 for SLB 9635 devices

to your device tree.
tpm_i2c_infineon is also retained as a compatible id as a fallback to
slb9635 protocol.

The driver was tested on Beaglebone.

4e11f848c6 dt: describe base reset signal binding
This binding is intended to represent the hardware reset signals present
internally in most IC (SoC, FPGA, ...) designs.
It consists of a binding for a reset controller device (provider), and a
pair of properties, "resets" and "reset-names", to link a device node
(consumer) to its reset controller via phandle, similarly to the clock
and interrupt bindings.

The reset controller has all information necessary to reset the consumer
device. That could be provided via device tree, or it could be implemented
in hardware.
The aim is to enable device drivers to request a framework API to issue a
reset simply by providing their struct device pointer as the most common
case.

41a2a4665d ACPI / PM: Expose lists of device wakeup power resources to user space
Commit 18a3870 (ACPI / PM: Expose lists of device power resources
to user space) exposed the lists of ACPI power resources associated
with power states of ACPI devices, but it didn't expose the lists
of ACPI wakeup power resources, which also is necessary to get the
full picture of dependencies between ACPI devices and power
resources.

For this reason, for every ACPI device node having a list of ACPI
wakeup power resources associated with it, expose that list to user
space in analogy with commit 18a3870.

209224862c net: mv643xx_eth: add shared clk and cleanup existing clk handling
This patch adds an optional shared block clock to avoid lockups on
clock gated controllers. Besides the new clock, clock handling for
existing clocks is cleaned up and moved to devm_clk_get. Device
tree binding documentation is updated for the new clocks property.

49d7b5bfb7 cpufreq: exynos: Add cpufreq driver for exynos5440
This patch adds dvfs support for exynos5440 SOC. This soc has 4 cores and
they scale at same frequency. The nature of exynos5440 clock controller is
different from previous exynos controllers so not using the common exynos
cpufreq framework. The major difference being interrupt notification for
frequency change. Also, OPP library is used for device tree parsing to get
different parameters like frequency, voltage etc. Since the opp library sorts
the frequency table in ascending order so they are again re-arranged in
descending order. This will have one-to-one mapping with the clock controller
state management logic.

Future AMD processors, starting with Family 16h, can provide software
with feedback on how the workload may respond to frequency change --
memory-bound workloads will not benefit from higher frequency, where
as compute-bound workloads will. This patch enables this "frequency
sensitivity feedback" to aid the ondemand governor to make better
frequency change decisions by hooking into the powersave bias.

27dd438542 ext4: introduce reserved space
Currently in ENOSPC condition when writing into unwritten space, or
punching a hole, we might need to split the extent and grow extent tree.
However since we can not allocate any new metadata blocks we'll have to
zero out unwritten part of extent or punched out part of extent, or in
the worst case return ENOSPC even though use actually does not allocate
any space.

Also in delalloc path we do reserve metadata and data blocks for the
time we're going to write out, however metadata block reservation is
very tricky especially since we expect that logical connectivity implies
physical connectivity, however that might not be the case and hence we
might end up allocating more metadata blocks than previously reserved.
So in future, metadata reservation checks should be removed since we can
not assure that we do not under reserve.

And this is where reserved space comes into the picture. When mounting
the file system we slice off a little bit of the file system space (2%
or 4096 clusters, whichever is smaller) which can be then used for the
cases mentioned above to prevent costly zeroout, or unexpected ENOSPC.

The number of reserved clusters can be set via sysfs, however it can
never be bigger than number of free clusters in the file system.

Note that this patch fixes the failure of xfstest 274 as expected.

2b07910131 ARM: tegra: clock driver development
This branch contains most fixes and enhancements to the Tegra common
 clock driver. The main new feature is a driver for Tegra114, which
 coupled with later device tree changes enables many devices on that
 chip, such as MMC, I2C, etc.
 
 This branch depends on a patch in:
 
 git://git.linaro.org/people/mturquette/linux.git clk-for-3.10
 
 Mike has stated that this branch is stable, and is aware of this
 dependency and merge.
 
 Mike's branch is based on v3.9-rc3, which includes a USB change which
 causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence,
 this branch pulls in v3.9-rc4 to ensure bisectability as much as
 possible.
 
 This branch is based on v3.9-rc4, followed by a merge of previous Tegra
 "soc" pull request, followed by a merge of clk-for-3.10.

3f551d6aca pinctrl: add pinctrl driver for imx6dl
The imx6dl is a derivative of imx6q with very limited difference.  These
two SoCs are so compatible that they can be handled as one platform in
software.  That said, we will not have target SOC_IMX6DL but just
reusing SOC_IMX6Q.   That's why the pinctrl-imx6dl driver is added here
with symbol PINCTRL_IMX6Q controlling the build of it.

e16415313c pinctrl: imx: move hard-coding data into device tree
Currently, all imx pinctrl drivers maintain a big array of struct
imx_pin_reg which hard-codes data like register offset and mux mode
setting for each pin function.  Every time a new imx SoC support is
added, we need to add such a big mount of data.  With moving to single
kernel build, it's only matter of time to be blamed on memory consuming.

With DTC pre-processor support in place, the patch moves all these data
into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and
changing the PIN_FUNC_ID parsing code a little bit.

The pin id gets re-numbered based on mux register offset, or config
register offset if the pin has no mux register, so that kernel can
identify the pin id from register offsets provided by device tree.

As a bonus point of the change, those arbitrary magic numbers standing
for particular PIN_FUNC_ID in device tree sources are now replaced by
macros to improve the readability of dts files.

e46980a10a mei: bus: Add device enabling and disabling API
It should be left to the drivers to enable and disable the device on the
MEI bus when e.g getting probed.
For drivers to be able to safely call the enable and disable hooks, the
mei_cl_ops must be set before it's probed and thus this should happen
before registering the device on the MEI bus. Hence the mei_cl_add_device()
prototype change.

bc34b5f27c ARM: sunxi: Rework the restart code
The Allwinner sun6i (A31) has a slightly different watchdog, that
doesn't allow to use the already existing restart code.

Rework a bit the restart code to allow to plug in more easily different
restart handlers depending on the device tree.

In the past, we were also meaning sunxi as a generic name covering all
Allwinner SoCs. This won't be true anymore with the A31 (sun6i) that
differs pretty much from sun4i and sun5i, and we will end up having
sunxi, for sun4i and sun5i, and sun6i, which is neither consistent nor
convenient. So, while we're at it, also change sunxi to sun4i.

d7fbc6ca35 irqchip: sunxi: Rename sunxi to sun4i
During the introduction of the Allwinner SoC platforms, sunxi was
initially meant as a generic name for all the variants of the Allwinner
SoC.

It was ok at the time of the support of only the A10 and A13 that
looks pretty much the same, but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...

Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.

393d1d1d76 ext4: implementation of a new ioctl called EXT4_IOC_SWAP_BOOT
Add a new ioctl, EXT4_IOC_SWAP_BOOT which swaps i_blocks and
associated attributes (like i_blocks, i_size, i_flags, ...) from the
specified inode with inode EXT4_BOOT_LOADER_INO (#5). This is
typically used to store a boot loader in a secure part of the
filesystem, where it can't be changed by a normal user by accident.
The data blocks of the previous boot loader will be associated with
the given inode.

This usercode program is a simple example of the usage:

int main(int argc, char *argv[])
{
  int fd;
  int err;

  if ( argc != 2 ) {
    printf("usage: ext4-swap-boot-inode FILE-TO-SWAP\n");
    exit(1);
  }

  fd = open(argv[1], O_WRONLY);
  if ( fd < 0 ) {
    perror("open");
    exit(1);
  }

  err = ioctl(fd, EXT4_IOC_SWAP_BOOT);
  if ( err < 0 ) {
    perror("ioctl");
    exit(1);
  }

  close(fd);
  exit(0);
}

Some Exynos-based boards contain secure firmware and must use firmware

This patch adds firmware operations for Exynos secure firmware and a way
for board code and device tree to specify that they must be used.

Example of use:

In board code:

          .init_early   = exynos_firmware_init,
          /* ... */
  MACHINE_END

In device tree:

  / {

          firmware@0203F000 {
                  compatible = "samsung,secure-firmware";
                  reg = <0x0203F000 0x1000>;

7366b92a77 ARM: Add interface for registering and calling firmware-specific operations
Some boards are running with secure firmware running in TrustZone secure
world, which changes the way some things have to be initialized.

This patch adds an interface for platforms to specify available firmware
operations and call them.

A wrapper macro, call_firmware_op(), checks if the operation is provided
and calls it if so, otherwise returns -ENOSYS to allow fallback to
legacy operation..

By default no operations are provided.

Example of use:

In code using firmware ops:

  __raw_writel(virt_to_phys(exynos4_secondary_startup),
               CPU1_BOOT_REG);

  /* Call Exynos specific smc call */
  if (call_firmware_op(cpu_boot, cpu) == -ENOSYS)
          cpu_boot_legacy(...); /* Try legacy way */

  gic_raise_softirq(cpumask_of(cpu), 1);

In board-/platform-specific code:

  static int platformX_do_idle(void)
  {
          /* tell platformX firmware to enter idle */
          return 0;
  }

  static int platformX_cpu_boot(int i)
  {
          /* tell platformX firmware to boot CPU i */
          return 0;
  }

  static const struct firmware_ops platformX_firmware_ops = {
          .do_idle      = exynos_do_idle,
          .cpu_boot     = exynos_cpu_boot,
          /* other operations not available on platformX */
  };

  static void __init board_init_early(void)
  {
          register_firmware_ops(&platformX_firmware_ops);
  }

Check for NULL before calling the following operations from "struct
ieee802154_mlme_ops": assoc_req, assoc_resp, disassoc_req, start_req,
and scan_req.

This fixes a current oops where those functions are called but not
implemented. It also updates the documentation to clarify that they
are now optional by design. If a call to an unimplemented function
is attempted, the kernel returns EOPNOTSUPP via netlink.

The following operations are still required: get_phy, get_pan_id,
get_short_addr, and get_dsn.

Note that the places where this patch changes the initialization
of "ret" should not affect the rest of the code since "ret" was
always set (again) before returning its value.

a7c69118bd hwmon: (pmbus/lm25066) Report VAUX as vmon
So far the driver reported the voltage on VAUX as "vout2". This was not
entirely appropriate as it is not an output voltage, and complicates
the code. Use the new virtual "VMON" register set and report the voltage
as "vmon" instead.

8c770f3a47 hwmon: (pmbus/ltc2978) Clean up documentation
Some sysfs attributes are only supported on LTC2978 and not on LTC3880.
Update documentation to reflect which attributes are supported for which chips.

Output current attributes supported on LTC3880 were described as providing
input current values. Fix text to reflect that the attributes provide output
current values.

"reset history" attribute descriptions were misleading and seemed to imply
that all history was reset when writing a single attribute. Replace with more
accurate text.

Replace 'internal temperature" with "chip temperature". Temperature limits
not only apply to the chip temperature, but also to external temperatures
on LTC3880, so remove the word "chip" from the attribute description.

51c2a4871c hwmon: (adt7410) Add support for the adt7310/adt7320
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map
layout is a bit different, i.e. the register addresses differ between the two
variants, but the bit layouts of the individual registers are identical. So both
chip variants can easily be supported by the same driver. The issue of non
matching register address layouts is solved by a simple look-up table which
translates the I2C addresses to the SPI addresses.

The patch moves the bulk of the adt7410 driver to a common module that will be
shared by the adt7410 and adt7310 drivers. This common module implements the
driver logic and uses a set of virtual functions to perform IO access. The
adt7410 and adt7310 driver modules provide proper implementations of these IO
accessor functions for I2C respective SPI.

f333a331ad spi/tegra114: add spi driver
Add SPI driver for NVIDIA's Tegra114 SPI controller. This controller
is different than the older SoCs SPI controller in internal design as
well as register interface.

This driver supports the:
- non DMA based transfer for smaller transfer i.e. less than FIFO depth.
- APB DMA based transfer for larger transfer i.e. more than FIFO depth.
- Clock gating through runtime PM callbacks.
- registration through DT only.

447b0c7b93 spi/spi-fsl-spi: Add support for Aeroflex Gaisler GRLIB cores normally running on SPARC
This adds support for the mostly register-compatible SPICTRL cores from the
GRLIB VHDL IP core library from Aeroflex Gaisler. They are normally running on
SPARC. A different entry in of_fsl_spi_match matches this core and indicates a
different hardware type that is used to set up different function pointers and
special cases.

The GRLIB core operates in cpu mode. The number of bits per word might be
limited. There might be native chipselects selected via a slave select
register. These differences to the FSL type cores, if present, are indicated by
a capabilities register. Other register and function differences exists but are
not relevant to the driver.

This makes the spi-fsl-spi driver usable in CPU mode outside of an FSL_SOC and
even an powerpc environment by moving CPM mode functionality to a separate file
that is only compiled and linked in an FSL_SOC environment and adding some
ifdefs to hide types and functions or provide alternatives.

For devicetree probing a "clock-frequency" property is used for clock frequency
instead of calls to FSL_SOC-specific functions.

64dc9e2e73 usb: patches for v3.10 merge window
Here is the big Gadget & PHY pull request. Many of us have
 been really busy lately getting multiple drivers to a better
 position.
 
 Since this pull request is so large, I will divide it in sections
 so it's easier to grasp what's included.
 
 - cleanups:
 	. UDC drivers no longer touch gadget->dev, that's now udc-core
 		responsibility
 	. Many more UDC drivers converted to usb_gadget_map/unmap_request()
 	. UDC drivers no longer initialize DMA-related fields from gadget's
 		device structure
 	. UDC drivers don't touch gadget.dev.driver directly
 	. UDC drivers don't assign gadget.dev.release directly
 	. Removal of some unused DMA_ADDR_INVALID
 	. Introduction of CONFIG_USB_PHY
 	. All phy drivers have been moved to drivers/usb/phy and renamed to
 		a common naming scheme
 	. Fix PHY layer so it never returns a NULL pointer, also fix all
 		callers to avoid using IS_ERR_OR_NULL()
 	. Sparse fixes all over the place
 	. drivers/usb/otg/ has been deleted
 	. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
 		usage
 
 - new features:
 	. UDC core now provides a generic way for tracking and reporting
 		UDC's state (not attached, resuming, suspended, addressed,
 		default, etc)
 	. twl4030-usb learned that it shouldn't be enabled during init
 	. Full DT support for DWC3 has been implemented
 	. ab8500-usb learned about pinctrl framework
 	. nop PHY learned about DeviceTree and regulators
 	. DWC3 learned about suspend/resume
 	. DWC3 can now be compiled in host-only and gadget-only (as well as
 		DRD) configurations
 	. UVC now enables streaming endpoint based on negotiated speed
 	. isp1301 now implements the PHY API properly
 	. configfs-based interface for gadget drivers which will lead to
 		the removal of all code which just combines functions together
 		to build functional gadget drivers.
 	. f_serial and f_obex were converted to new configfs interface while
 		maintaining old interface around.
 
 - non-critical fixes:
 	. UVC gadget driver got fixes for Endpoint usage and stream calculation
 	. ab8500-usb fixed unbalanced clock and regulator API usage
 	. twl4030-usb got a fix for when OMAP3 is booted with cable connected
 	. fusb300_udc got a fix for DMA usage
 	. UVC got fixes for two assertions of the USB Video Class Compliance
 		specification revision 1.1
 	. build warning issues caused by recent addition of __must_check to
 		regulator API
 
 These are all changes which deserve a mention, all other changes are related
 to these one or minor spelling fixes and other similar tasks.

The 'camera' DT node needs to have sclk_cam0/1 and pxl_async0/1 clocks
specified, while 'fimc' nodes should have only "fimc" and "sclk_fimc".
"mux" and "parent" are leftovers from early versions of patches adding
DT support, when the IP bus clock parent clock was being set by the
driver. A better solution is needed to have e.g. clocks driver setting
all required parent clocks, before clock consumers start using the
clocks. Currently this binding doesn't describe parent clocks setup,
it needs to be specified and handled somewhere else.

8fc24426f1 Revert "ALSA: hda - Allow power_save_controller option override DCAPS"
This reverts commit 6ab317419c.

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option
override DCAPS] changed the behavior of power_save_controller so that
it can override the driver capability.  This assumed that this option
is rarely changed dynamically unlike power_save option.  Too naive.

It turned out that the user-space power-management tool tries to set
power_save_controller option to 1 together with power_save option
without knowing what's actually doing.  This enabled forcibly the
runtime PM of the controller,  which is known to be broken om many
chips thus disabled as default.

So, the only sane fix is to revert this commit again.  It was intended
to ease debugging/testing for runtime PM enablement, but obviously we
need another way for it.

7ab0a48420 video: fb: vt8500: Convert framebuffer drivers to standardized binding
Now that a display timing binding is available, convert our almost identical
binding to use the standard binding.

This patch converts the vt8500 and wm8505 framebuffer drivers and
associated dts/dtsi files to use the standard binding as defined in
bindings/video/display-timing.txt.

There are two side-effects of making this conversion:

1) The fb node should now be in the board file, rather than the soc file as
the display-timing node is a child of the fb node.

2) We still require a bits per pixel property to initialize the framebuffer
for the different lcd panels. Rather than including this as part of the
display timing, it is moved into the framebuffer node.

I have also taken the opportunity to alphabetise the includes of each
driver to avoid double-ups.

32cde0b514 ARM: OMAP2+: Convert ONENAND to retrieve GPMC settings from DT
When booting with device-tree, retrieve GPMC settings for ONENAND from
the device-tree blob. This will allow us to remove all static settings
stored in the gpmc-nand.c in the future once the migration to
device-tree is complete.

The user must now specify the ONENAND device width in the device-tree
binding so that the GPMC can be programmed correctly. Therefore, update
the device-tree binding documentation for ONENAND devices connected to
the GPMC to reflect this.

Please note that this does not include GPMC timings for ONENAND. The
timings are being calculated at runtime.

There is some legacy code that only enables read wait monitoring for
non-OMAP3 devices. There are no known OMAP3 device issues that prevent
this feature being enabled and so when booting with device-tree use the
wait-monitoring settings described in the device-tree blob.

d36b4cd46d ARM: OMAP2+: Add additional GPMC timing parameters
Some of the GPMC timings parameters are currently missing from the GPMC
device-tree binding. Add these parameters to the binding documentation
as well as code to read them. Also add either "-ps" or "-ns" suffix to
the GPMC timing properties to indicate whether the timing is in
picoseconds or nanoseconds.

The existing code in gpmc_read_timings_dt() is checking the value of
of_property_read_u32() and only is successful storing the value read
in the gpmc_timings structure. Checking the return value in this case
is not necessary and we can simply read the value, if present, and
store directly in the gpmc_timings structure. Therefore, simplify the
code by removing these checks.

The comment in the gpmc_read_timings_dt() function, "only for OMAP3430"
is also incorrect as it is applicable to all OMAP3+ devices. So correct
this too.

3451d0243c nohz: Rename CONFIG_NO_HZ to CONFIG_NO_HZ_COMMON
We are planning to convert the dynticks Kconfig options layout
into a choice menu. The user must be able to easily pick
any of the following implementations: constant periodic tick,
idle dynticks, full dynticks.

As this implies a mutual exclusion, the two dynticks implementions
need to converge on the selection of a common Kconfig option in order
to ease the sharing of a common infrastructure.

It would thus seem pretty natural to reuse CONFIG_NO_HZ to
that end. It already implements all the idle dynticks code
and the full dynticks depends on all that code for now.
So ideally the choice menu would propose CONFIG_NO_HZ_IDLE and
CONFIG_NO_HZ_EXTENDED then both would select CONFIG_NO_HZ.

On the other hand we want to stay backward compatible: if
CONFIG_NO_HZ is set in an older config file, we want to
enable CONFIG_NO_HZ_IDLE by default.

But we can't afford both at the same time or we run into
a circular dependency:

1) CONFIG_NO_HZ_IDLE and CONFIG_NO_HZ_EXTENDED both select
   CONFIG_NO_HZ
2) If CONFIG_NO_HZ is set, we default to CONFIG_NO_HZ_IDLE

We might be able to support that from Kconfig/Kbuild but it
may not be wise to introduce such a confusing behaviour.

So to solve this, create a new CONFIG_NO_HZ_COMMON option
which gathers the common code between idle and full dynticks
(that common code for now is simply the idle dynticks code)
and select it from their referring Kconfig.

Then we'll later create CONFIG_NO_HZ_IDLE and map CONFIG_NO_HZ
to it for backward compatibility.

83d435dd6e Fix example error_injection_tool
I got a "sched_setaffinity:: Invalid argument" error when using
err_injection_tool to inject error on a system with over 32 cpus.

Error information when injecting an error on a system with over 32 cpus:
$ ./err_injection_tool -i
/sys/devices/system/cpu/cpu0/err_inject//err_type_info

Configurations:
On cpu32: loop=10, interval=5(s) err_type_info=4101,err_struct_info=95
Error sched_setaffinity:: Invalid argument
All done

This because there is overflow when calculating the cpumask: the
type of (1<<k) is int, while mask[j] is unsigned long. When k > 31,
(1<<k) is truncated to ZERO, resulting in a unexpected cpumask.

8a67f0ef2b cpufreq: ARM big LITTLE: Add generic cpufreq driver and its DT glue
big LITTLE is ARM's new Architecture focussing power/performance needs of modern
world. More information about big LITTLE can be found here:

http://www.arm.com/products/processors/technologies/biglittleprocessing.php
http://lwn.net/Articles/481055/

In order to keep cpufreq support for all big LITTLE platforms simple/generic,
this patch tries to add a generic cpufreq driver layer for all big LITTLE
platforms.

The driver is divided into two parts:
- Core driver: Generic and shared across all big LITTLE SoC's
- Glue drivers: Per platform drivers providing ops to the core driver

This patch adds in a generic glue driver which would extract information from
Device Tree.

Future SoC's can either reuse the DT glue or write their own depending on the
need.

Merge tag 'v3.9-rc5' into wq/for-3.10

Writeback conversion to workqueue will be based on top of wq/for-3.10
branch to take advantage of custom attrs and NUMA support for unbound
workqueues.  Mainline currently contains two commits which result in
non-trivial merge conflicts with wq/for-3.10 and because
block/for-3.10/core is based on v3.9-rc3 which contains one of the
conflicting commits, we need a pre-merge-window merge anyway.  Let's
pull v3.9-rc5 into wq/for-3.10 so that the block tree doesn't suffer
from workqueue merge conflicts.

The two conflicts and their resolutions:

* e68035fb65 ("workqueue: convert to idr_alloc()") in mainline changes
  worker_pool_assign_id() to use idr_alloc() instead of the old idr
  interface.  worker_pool_assign_id() goes through multiple locking
  changes in wq/for-3.10 causing the following conflict.

  static int worker_pool_assign_id(struct worker_pool *pool)
  {
	  int ret;

  <<<<<<< HEAD
	  lockdep_assert_held(&wq_pool_mutex);

	  do {
		  if (!idr_pre_get(&worker_pool_idr, GFP_KERNEL))
			  return -ENOMEM;
		  ret = idr_get_new(&worker_pool_idr, pool, &pool->id);
	  } while (ret == -EAGAIN);
  =======
	  mutex_lock(&worker_pool_idr_mutex);
	  ret = idr_alloc(&worker_pool_idr, pool, 0, 0, GFP_KERNEL);
	  if (ret >= 0)
		  pool->id = ret;
	  mutex_unlock(&worker_pool_idr_mutex);
  >>>>>>> c67bf5361e7e66a0ff1f4caf95f89347d55dfb89

	  return ret < 0 ? ret : 0;
  }

  We want locking from the former and idr_alloc() usage from the
  latter, which can be combined to the following.

  static int worker_pool_assign_id(struct worker_pool *pool)
  {
	  int ret;

	  lockdep_assert_held(&wq_pool_mutex);

	  ret = idr_alloc(&worker_pool_idr, pool, 0, 0, GFP_KERNEL);
	  if (ret >= 0) {
		  pool->id = ret;
		  return 0;
	  }
	  return ret;
   }

* eb2834285c ("workqueue: fix possible pool stall bug in
  wq_unbind_fn()") updated wq_unbind_fn() such that it has single
  larger for_each_std_worker_pool() loop instead of two separate loops
  with a schedule() call inbetween.  wq/for-3.10 renamed
  pool->assoc_mutex to pool->manager_mutex causing the following
  conflict (earlier function body and comments omitted for brevity).

  static void wq_unbind_fn(struct work_struct *work)
  {
  ...
		  spin_unlock_irq(&pool->lock);
  <<<<<<< HEAD
		  mutex_unlock(&pool->manager_mutex);
	  }
  =======
		  mutex_unlock(&pool->assoc_mutex);
  >>>>>>> c67bf5361e7e66a0ff1f4caf95f89347d55dfb89

		  schedule();

  <<<<<<< HEAD
	  for_each_cpu_worker_pool(pool, cpu)
  =======
  >>>>>>> c67bf5361e7e66a0ff1f4caf95f89347d55dfb89
		  atomic_set(&pool->nr_running, 0);

		  spin_lock_irq(&pool->lock);
		  wake_up_worker(pool);
		  spin_unlock_irq(&pool->lock);
	  }
  }

  The resolution is mostly trivial.  We want the control flow of the
  latter with the rename of the former.

  static void wq_unbind_fn(struct work_struct *work)
  {
  ...
		  spin_unlock_irq(&pool->lock);
		  mutex_unlock(&pool->manager_mutex);

		  schedule();

		  atomic_set(&pool->nr_running, 0);

		  spin_lock_irq(&pool->lock);
		  wake_up_worker(pool);
		  spin_unlock_irq(&pool->lock);
	  }
  }

d55262c4d1 workqueue: update sysfs interface to reflect NUMA awareness and a kernel param to disable NUMA affinity
Unbound workqueues are now NUMA aware.  Let's add some control knobs
and update sysfs interface accordingly.

* Add kernel param workqueue.numa_disable which disables NUMA affinity
  globally.

* Replace sysfs file "pool_id" with "pool_ids" which contain
  node:pool_id pairs.  This change is userland-visible but "pool_id"
  hasn't seen a release yet, so this is okay.

* Add a new sysf files "numa" which can toggle NUMA affinity on
  individual workqueues.  This is implemented as attrs->no_numa whichn
  is special in that it isn't part of a pool's attributes.  It only
  affects how apply_workqueue_attrs() picks which pools to use.

After "pool_ids" change, first_pwq() doesn't have any user left.
Removed.

2b13f7d4e3 [media] s5p-fimc: Add device tree based sensors registration
The sensor (I2C and/or SPI client) devices are instantiated by their
corresponding control bus drivers. Since the I2C client's master clock
is often provided by a video bus receiver (host interface) or other
than I2C/SPI controller device, the drivers of those client devices
are not accessing hardware in their driver's probe() callback. Instead,
after enabling clock, the host driver calls back into a sub-device
when it wants to activate them. This pattern is used by some in-tree
drivers and this patch also uses it for DT case. This patch is intended
as a first step for adding device tree support to the S5P/Exynos SoC
camera drivers. The second one is adding support for asynchronous
sub-devices registration and clock control from sub-device driver
level. The bindings shall not change when asynchronous probing support
is added.

e3276998da clk: sunxi: rename compatible strings
During the introduction of the Allwinner SoC platforms, sunxi was
initially meant as a generic name for all the variants of the Allwinner
SoC.

It was ok at the time of the support of only the A10 and A13 that
look pretty much the same; but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...

Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.

c0f4dfd4f9 rcu: Make RCU_FAST_NO_HZ take advantage of numbered callbacks
Because RCU callbacks are now associated with the number of the grace
period that they must wait for, CPUs can now take advance callbacks
corresponding to grace periods that ended while a given CPU was in
dyntick-idle mode.  This eliminates the need to try forcing the RCU
state machine while entering idle, thus reducing the CPU intensiveness
of RCU_FAST_NO_HZ, which should increase its energy efficiency.

a488985851 rcu: Distinguish "rcuo" kthreads by RCU flavor
Currently, the per-no-CBs-CPU kthreads are named "rcuo" followed by
the CPU number, for example, "rcuo".  This is problematic given that
there are either two or three RCU flavors, each of which gets a per-CPU
kthread with exactly the same name.  This commit therefore introduces
a one-letter abbreviation for each RCU flavor, namely 'b' for RCU-bh,
'p' for RCU-preempt, and 's' for RCU-sched.  This abbreviation is used
to distinguish the "rcuo" kthreads, for example, for CPU 0 we would have
"rcuob/0", "rcuop/0", and "rcuos/0".

3edce1cf81 USB: cdc-wdm: implement IOCTL_WDM_MAX_COMMAND
Userspace applications need to know the maximum supported message
size.

The cdc-wdm driver translates between a character device stream
and a message based protocol.  Each message is transported as a
usb control message with no further encapsulation or syncronization.
Each read or write on the character device should translate to
exactly one usb control message to ensure that message boundaries
are kept intact.  That means that the userspace application must
know the maximum message size supported by the device and driver,
making this size a vital part of the cdc-wdm character device API.

CDC WDM and CDC MBIM functions export the maximum supported
message size through CDC functional descriptors.  The cdc-wdm and
cdc_mbim drivers will parse these descriptors and use the value
chosen by the device.  The only current way for a userspace
application to retrive the value is by duplicating the descriptor
parsing. This is an unnecessary complex task, and application
writers are likely to postpone it, using a fixed value and adding
a "todo" item.

QMI functions have no way to tell the host what message size they
support.  The qmi_wwan driver use a fixed value based on protocol
recommendations and observed device behaviour.  Userspace
applications must know and hard code the same value.  This scheme
will break if we ever encounter a QMI device needing a device
specific message size quirk.  We are currently unable to support
such a device because using a non default size would break the
implicit userspace API.

The message size is currently a hidden attribute of the cdc-wdm
userspace API.  Retrieving it is unnecessarily complex, increasing
the possibility of drivers and applications using different limits.
The resulting errors are hard to debug, and can only be replicated
on identical hardware.

Exporting the maximum message size from the driver simplifies the
task for the userspace application, and creates a unified
information source independent of device and function class. It also
serves to document that the message size is part of the cdc-wdm
userspace API.

This proposed API extension has been presented for the authors of
userspace applications and libraries using the current API: libmbim,
libqmi, uqmi, oFono and ModemManager.  The replies were:

Aleksander Morgado:
 "We do really need max message size for MBIM; and as you say, it may be
  good to have the max message size info also for QMI, so the new ioctl
  seems a good addition. So +1 from my side, for what it's worth."

Dan Williams:
 "Yeah, +1 here.  I'd prefer the sysfs file, but the fact that that
  doesn't work for fd passing pretty much kills it."

No negative replies are so far received.

ef994fda44 First set of IIO new drivers and cleanup for the 3.10 cycle.
New stuff
 
 1) Add OF support for specifying mappings between iio devices and their
    in kernel consumers.
 2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and
    ad7924 added later in series)
 3) Driver for Exynos adc (dt suppor for phy added later in series).
 4) Make iio_push_event save IRQ context - necessary if it is to be used
    within an interrupt handler.  Users of this functionality to follow.
 5) For iio use the device tree node name to provide the hwmon name attribute
    if available.
 
 Removal and moves out of staging
 
 1) Drop the adt7410 driver from IIO now that there is a hmwon driver with
    equivalent support. This device is very much targeted at hardware
    monitoring so hwmon is a more appropriate host for the driver.
 2) Move iio_hwmon driver to drivers/hwmon.
 
 Cleanups
 
 1) Minor cleanup in ST common library.
 2) Large set of patches to break the info_mask element which previously used
 odd and even bits to specify if a channel attribute was either shared across
 similar channels or specific to only one.  Now we have two bitmaps, one for
 those parameters that are specific to this channel and one for those shared
 by all channels with the same type as this one.  This has no effect on the
 userspace abi. It simplifies the core code and provides more space for new
 channel parameters. It has been on the todo list for a long time!

97f00f7120 SSBI: Convert SSBI to device tree
The SSBI bus is exclusive to the Qualcomm MSM targets, and all SoCs
using it will be using device tree.  Convert this driver to indentify
with device tree.

This makes the bus probing a good bit simpler, since the attaching of
child nodes can be represented directly in the devicetree, rather than
having to be inferred by name.

4c64f1f70c dsa: fix device tree binding documentation typo on #address-cells
The device tree binding documentation for dsa explicitely states that a
DSA node should have its #address-cells property set to 2, yet the
example still used 1, fix that typo.
