c1f732ad76 GenWQE: Add sysfs interface for bitstream reload
This patch adds an interface on sysfs for userspace to request a card
bitstream reload. It sets the appropriate register and try to perform a
fundamental reset on the PCIe slot for the card to reload the bitstream
from the chosen partition.

0a58471541 ARM: SoC cleanups for 3.16
Cleanups for 3.16. Among these are:
 
 - A bunch of misc cleanups for Broadcom platforms, mostly housekeeping
 - Enabling Common Clock Framework on the older s3c24xx Samsung chipsets
 - Cleanup of the Versatile Express system controller code, moving it to syscon
 - Power management cleanups for OMAP platforms
 
 + a handful of other cleanups across the place

1690e35f9b misc: atmel_pwm: only build for supported platforms
There is architecture code in mach-at91 that depends on the
CONFIG_ATMEL_PWM symbol in order to call the soc-specific
at91_add_device_pwm function. While all of this is about code
that will be removed in the future, using DT probing and
the PWM framework, we currently get a build failure:

arch/arm/mach-at91/built-in.o: In function `at91_pwm_leds':
arch/arm/mach-at91/leds.c:88: undefined reference to `at91_add_device_pwm'

This patch ensures we only try to build this driver on
platforms on which it will build and work.

fd1a73c60e misc: pch_phub: Fix Kconfig dependencies
The pch_phub driver is for a companion chip to the Intel Atom E600
series processors. These are 32-bit x86 processors so the driver is
only needed on X86_32. Add COMPILE_TEST as an alternative, so that the
driver can still be build-tested elsewhere.

974cc7b934 mfd: vexpress: Define the device as MFD cells
This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:

* LEDs code has been completely removed and replaced with
  "gpio-leds" nodes in the tree (referencing dedicated
  GPIO subnodes in sysreg - bindings documentation updated);
  this also better fits the reality as some variants of the
  motherboard don't have all the LEDs populated

* syscfg bridge code has been extracted into a separate
  driver (placed in drivers/misc for no better place)

* all the ID & MISC registers are defined as sysconf
  making them available for other drivers should they need
  to use them (and also to the user via /sys/kernel/debug/regmap
  which can be helpful in platform debugging)

e4d8270e60 mei: set connecting state just upon connection request is sent to the fw
Adding power gating introduced new waiting state for client also during
connection attempt, a connection request can be queued for later either due
device is power gated or due to other on going connection.
We setting client connection state before start of full connect procedure so
in both cased the client state will be MEI_FILE_CONNECTING
which create interlock between the two connection attempts, both
detecting that another connection is in progress.

The interlock is resolved by moving client to connecting state
only upon connection request transmission, so the  first
cb in queue can be processed.

When moving cbs to the completion list we should not look at

write, the fact that a cb is on the write waiting list means
that it was already written to the HW and we can safely complete it.

Same pays for wait in poll handler, we do not have to check the state

c70929147a sound updates for 3.15-rc1
There have been lots of changes in ALSA core, HD-audio and ASoC, also
 most of PCI drivers touched by conversions of printks.  All these
 resulted in a high volume and wide ranged patch sets in this release.
 Many changes are fairly trivial, but also lots of nice cleanups and
 refactors.  There are a few new drivers, most notably, the Intel
 Haswell and Baytrail ASoC driver.
 
 Core changes:
 - A bit modernization; embed the device struct into snd_card struct,
   so that it may be referred from the beginning.  A new snd_card_new()
   function is introduced for that, and all drivers have been
   converted.
 
 - Simplification in the device management code in ALSA core;
   now managed by a simple priority list instead
 
 - Converted many kernel messages to use the standard dev_err() & co;
   this would be the pretty visible difference, especially for
   HD-audio.
 
 HD-audio:
 - Conexant codecs use the auto-parser as default now;
   the old static code still remains in case of regressions.
   Some old quirks have been rewritten with the fixups for auto-parser.
 
 - C-Media codecs also use the auto-parser as default now, too.
 
 - A device struct is assigned to each HD-audio codec, and the formerly
   hwdep attributes are accessible over the codec sysfs, too.
   hwdep attributes still remain for compatibility.
 
 - Split the PCI-specific stuff for HD-audio controller into a separate
   module, ane make a helper module for the generic controller driver.
   This is a preliminary change for supporting Tegra HDMI controller in
   near future, which slipped from 3.15 merge.
 
 - Device-specific fixes: mute LED support for Lenovo Ideapad,
   mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more
   Dell laptop headset quirks

Merge tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There have been lots of changes in ALSA core, HD-audio and ASoC, also
  most of PCI drivers touched by conversions of printks.  All these
  resulted in a high volume and wide ranged patch sets in this release.
  Many changes are fairly trivial, but also lots of nice cleanups and
  refactors.  There are a few new drivers, most notably, the Intel
  Haswell and Baytrail ASoC driver.

  Core changes:
   - A bit modernization; embed the device struct into snd_card struct,
     so that it may be referred from the beginning.  A new
     snd_card_new() function is introduced for that, and all drivers
     have been converted.

   - Simplification in the device management code in ALSA core; now
     managed by a simple priority list instead

   - Converted many kernel messages to use the standard dev_err() & co;
     this would be the pretty visible difference, especially for
     HD-audio.

  HD-audio:
   - Conexant codecs use the auto-parser as default now; the old static
     code still remains in case of regressions.  Some old quirks have
     been rewritten with the fixups for auto-parser.

   - C-Media codecs also use the auto-parser as default now, too.

   - A device struct is assigned to each HD-audio codec, and the
     formerly hwdep attributes are accessible over the codec sysfs, too.
     hwdep attributes still remain for compatibility.

   - Split the PCI-specific stuff for HD-audio controller into a
     separate module, ane make a helper module for the generic
     controller driver.  This is a preliminary change for supporting
     Tegra HDMI controller in near future, which slipped from 3.15
     merge.

   - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
     fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
     laptop headset quirks

   - Make the HD-audio codec response a bit more robust

   - A few improvements on Realtek ALC282 / 283 about the pop noises

   - A couple of Intel HDMI fixes

  ASoC:
   - Lots of cleanups for enumerations; refactored lots of error prone
     original codes to use more modern APIs

   - Elimination of the ASoC level wrappers for I2C and SPI moving us
     closer to converting to regmap completely and avoiding some
     randconfig hassle

   - Provide both manually and transparently locked DAPM APIs rather
     than a mix of the two fixing some concurrency issues

   - Start converting CODEC drivers to use separate bus interface
     drivers rather than having them all in one file helping avoid
     dependency issues

   - DPCM support for Intel Haswell and Bay Trail platforms, lots of
     fixes

   - Lots of work on improvements for simple-card, DaVinci and the
     Renesas rcar drivers.

   - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
     the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8

   - Fixes for the simple-card DAI format DT mess

   - DT support for a couple more devices.

   - Use of the tdm_slot mapping in a few drivers

   - Support of reset_resume callback for improved S4 in USB-audio
