ACPI and power management updates for 3.18-rc1

 - Rework the handling of wakeup IRQs by the IRQ core such that
   all of them will be switched over to "wakeup" mode in
   suspend_device_irqs() and in that mode the first interrupt
   will abort system suspend in progress or wake up the system
   if already in suspend-to-idle (or equivalent) without executing
   any interrupt handlers.  Among other things that eliminates the
   wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
   flag with interrupts which don't really need it and should not
   use it (Thomas Gleixner and Rafael J Wysocki).

 - Switch over ACPI to handling wakeup interrupts with the help
   of the new mechanism introduced by the above IRQ core rework
   (Rafael J Wysocki).

 - Rework the core generic PM domains code to eliminate code that's
   not used, add DT support and add a generic mechanism by which
   devices can be added to PM domains automatically during
   enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).

 - Add debugfs-based mechanics for debugging generic PM domains
   (Maciej Matraszek).

 - ACPICA update to upstream version 20140828.  Included are updates
   related to the SRAT and GTDT tables and the _PSx methods are in
   the METHOD_NAME list now (Bob Moore and Hanjun Guo).

 - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
   can't really be done in a straightforward way) to prevent
   Thunderbolt from being turned off on Apple systems after boot
   (or after resume from system suspend) and rework the ACPI Smart
   Battery Subsystem (SBS) driver to work correctly with Apple
   platforms (Matthew Garrett and Andreas Noever).

 - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
   code, adding support for 133MHz I2C source clock on Intel Baytrail
   to it and making it avoid using UART RTS override with Auto Flow
   Control (Heikki Krogerus).

 - ACPI backlight updates removing the video_set_use_native_backlight
   quirk which is not necessary any more, making the code check the
   list of output devices returned by the _DOD method to avoid
   creating acpi_video interfaces that won't work and adding a quirk
   for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).

 - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).

 - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
   Sudip Mukherjee, Yijing Wang, and Zhang Rui).

 - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
   Rasmus Villemoes).

 - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
   change among other things), ppc-corenet, powernv (Viresh Kumar,
   Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).

 - cpuidle support for DT-based idle states infrastructure, new
   ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
   Rasmus Villemoes).

 - ARM big.LITTLE cpuidle driver updates: support for DT-based
   initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
   Kevin Hilman).

 - Rework of the test_suspend kernel command line argument and
   a new trace event for console resume (Srinivas Pandruvada,
   Todd E Brandt).

 - Second attempt to optimize swsusp_free() (hibernation core) to
   make it avoid going through all PFNs which may be way too slow on
   some systems (Joerg Roedel).

 - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).

 - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
   entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).

 - PM core fix related to clock management (Geert Uytterhoeven).

 - PM core's sysfs code cleanup (Johannes Berg).

qcomlt-v3.17

This is the 3.12.30 stable release

This is the bulk of GPIO changes for the v3.18 development
cycle:

- Increase the default ARCH_NR_GPIO from 256 to 512. This
  was done to avoid having a custom <asm/gpio.h> header for
  the x86 architecture - GPIO is custom and complicated
  enough as it is already! We want to move to a radix to
  store the descriptors going forward, and finally get rid
  of this fixed array size altogether.

- Endgame patching of the gpio_remove() semantics initiated
  by Abdoulaye Berthe. It is not accepted by the system that
  the removal of a GPIO chip fails during e.g. reboot or
  shutdown, and therefore the return value has now painfully
  been refactored away. For special cases like GPIO expanders
  on a hot-pluggable bus like USB, we may later add some
  gpiochip_try_remove() call, but for the cases we have now,
  return values are moot.

- Some incremental refactoring of the gpiolib core and ACPI
  GPIO library for more descriptor usage.

- Refactor the chained IRQ handler set-up method to handle
  also threaded, nested interrupts and set up the parent IRQ
  correctly. Switch STMPE and TC3589x drivers to use this
  registration method.

- Add a .irq_not_threaded flag to the struct gpio_chip, so
  that also GPIO expanders that block but are still not
  using threaded IRQ handlers.

- New drivers for the ARM64 X-Gene SoC GPIO controller.

- The syscon GPIO driver has been improved to handle the
  "DSP GPIO" found on the TI Keystone 2 SoC:s.

- ADNP driver switched to use gpiolib irqchip helpers.

- Refactor the DWAPB driver to support being instantiated
  from and MFD cell (platform device).

- Incremental feature improvement in the Zynq, MCP23S08,
  DWAPB, OMAP, Xilinx and Crystalcove drivers.

- Various minor fixes.

regulator: Updates for v3.18

This time around most of the changes are a lot of new drivers along with
the standard set of fixes and cleanups (thanks again largely to Axel
Lin).  We do have one nice new feature in the core which factors out the
disappointingly tricky code around DT parsing, only a couple of drivers
have been converted so far:

 - Factor out the code for parsing the standard bindings for a set of
   regulators out of DT, making the probe part of a lot of drivers
   simplier.
 - New drivers for Dialog DA9213, HiSilicon HI6420, Intersil ISL9305/H,
   Ricoh RN5T618, Rockchip RK808, Skyworks SKY81452, Silergy SYR82x, and
   Qualcomm RPM.

ASoC: Updates for v3.18

 - More componentisation work from Lars-Peter, this time mainly
   cleaning up the suspend and bias level transition callbacks.
 - Real system support for the Intel drivers and a bunch of fixes and
   enhancements for the associated CODEC drivers, this is going to need
   a lot quirks over time due to the lack of any firmware description of
   the boards.
 - Jack detect support for simple card from Dylan Reid.
 - A bunch of small fixes and enhancements for the Freescale drivers.
 - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32, Everest
   Semiconductor ES8328 and Freescale cards using the ASRC in newer i.MX
   processors.

This is the 3.10.56 stable release

This is the 3.14.20 stable release

This is the 3.16.4 stable release

Linux 3.17

regulator: Simplified OF matching

Provide a simplified way of matching regulators in DT in order to save
some fiddly code in drivers.

- first batch of skl stage 1 enabling
- fixes from Rodrigo to the PSR, fbc and sink crc code
- kerneldoc for the frontbuffer tracking code, runtime pm code and the basic
  interrupt enable/disable functions
- smaller stuff all over

ACPI and power management fixes for final 3.17

 - A recent cpufreq core fix went too far and introduced a regression
   in the system suspend code path.  Fix from Viresh Kumar.

 - An ACPI-related commit in the i915 driver that fixed backlight
   problems for some Thinkpads inadvertently broke a Dell machine
   (in 3.16).  Fix from Aaron Lu.

 - The pcc-cpufreq driver was broken during the 3.15 cycle by a
   commit that put wait_event() under a spinlock by mistake.  Fix
   that (Rafael J Wysocki).

 - The return value type of integrator_cpufreq_remove() is void, but
   should be int.  Fix from Arnd Bergmann.

media fixes for v3.17-rc8

This patch adds the support for the Meson6 watchdog in the DTSI

sound fixes for 3.17-final

Just a few pending bits of random fixes in ASoC.  Nothing
exciting, but would be nice to be merged in 3.17, as most of
them are also for stable kernels.

This is the 3.12.29 stable release
