GPIO bulk changes for the v3.13 development cycle

- Merged the GPIO descriptor API from Alexandre Courbot.
  This is a first step toward trying to get rid of the
  global GPIO numberspace for the future.

- Add an API so that driver can flag that a certain GPIO
  line is being used by a irqchip backend for generating
  IRQs, so that we can enforce checks, like not allowing
  users to switch that line to an output at runtime, since
  this makes no sense. Implemented corresponding calls
  in a few select drivers.

- ACPI GPIO cleanups, refactorings and switch to using the
  descriptor-based interface.

- Support for the TPS80036 Palmas GPIO variant.

- A new driver for the Broadcom Kona GPIO SoC IP block.

- Device tree support for the PCF857x driver.

- A set of ARM GPIO refactorings with the goal of getting
  rid of a bunch of custom GPIO implementations from the
  arch/arm/* tree:

  - Move the IOP GPIO driver to the GPIO subsystem and
    fix all users to use the gpiolib API for accessing
    GPIOs. Delete the old custom GPIO implementation.

  - Delete the unused custom PXA GPIO implemention.

  - Convert all users of the IXP4 custom GPIO
    implementation to use gpiolib and delete the custom
    implementation.

  - Delete the custom Gemini GPIO implementation, also
    completely unused.

- Various cleanups and renamings.

Main pin control pull request for the v3.13 cycle:

- Blackfin ADI pin control driver, we move yet another
  architecture under this subsystem umbrella.

- Incremental updates to the Renesas Super-H PFC pin control
  driver. New subdriver for the r8a7791 SoC.

- Non-linear GPIO ranges from the gpiolib side of things,
  this enabled simplified device tree bindings by referring
  entire groups of pins on some pin controller to act as
  back-end for a certain GPIO-chip driver.

- Add the Abilis TB10x pin control driver used on the ARC
  architecture. Also the corresponding GPIO driver is merged
  through this tree, so the ARC has full support for pins
  and GPIOs after this.

- Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin
  controller instances. The i.MX1 and i.MX27 is an entirely
  new family (silicon) of controllers whereas i.MX50 is
  a variant of the previous supported controller.

- Then the usual slew of fixes, cleanups and incremental
  updates.

Linux 3.12

Last-minute ACPI and power management fixes for 3.12

 - Revert epoll and select commits related to the freezer, introduced
   during the 3.11 cycle, that cause mysterious user space breakage
   to occur during resume from suspend to RAM for multiple users of
   32-bit x86 systems.  Material for 3.11.y stable kernels.

 - Revert a recent ACPI-based PCI hotplug (ACPIPHP) commit that was
   part of boot problem fixes for one machine, but turns out to cause
   issues with hotplug on Thunderbolt chains with multiple devices.
   It also turns out to be unnecessary after another fix in the
   same area that went in later.  From Mika Westerberg.

drm/tegra: Changes for v3.13-rc1

The biggest part of the changes is the decoupling of the host1x and DRM
drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra
from whence it came. There is a lot of cleanup as well, and the drivers
can now be properly unloaded and reloaded.

HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen.

gr2d support was extended to Tegra114 and the gr3d driver that has been
in the works for quite some time finally made it in. All pieces to run
an OpenGL driver on top of an upstream kernel are now available.

Support for syncpoint bases was added by Arto Merilainen. This is useful
for synchronizing between command streams from different engines such as
gr2d and gr3d.

Erik Faye-Lund and Wei Yongjun contributed various small fixes. Thanks!

Linux 3.12-rc7

This is the 3.2.52 stable release

ACPI and power management fixes for 3.12-rc7

 - Fix for rounding errors in intel_pstate causing CPU utilization to
   be underestimated from Brennan Shacklett.

 - intel_pstate fix to always use the correct max pstate value when
   computing the min pstate from Dirk Brandewie.

 - Hibernation fix for deadlocking resume in cases when the probing
   of the device containing the image is deferred from Russ Dill.

 - acpi-cpufreq fix to prevent the module from staying in memory
   when the driver cannot be registered and then attempting to
   unregister things that have never been registered on exit.

Linux 3.12-rc6

ACPI and power management fixes for 3.12-rc6

 - intel_pstate fix for misbehavior after system resume if sysfs
   attributes are set in a specific way before the corresponding
   suspend from Dirk Brandewie.

 - A recent intel_pstate fix has no effect if unsigned long is 32-bit,
   so fix it up to cover that case as well.

 - The s3c64xx cpufreq driver was not updated when the index field of
   struct cpufreq_frequency_table was replaced with driver_data, so
   update it now.  From Charles Keepax.

 - The Kconfig help text for ACPI_BUTTON still refers to /proc/acpi/event
   that has been dropped recently, so modify it to remove that reference.
   From Krzysztof Mazur.

 - A Lan Tianyu's change adds a missing mutex unlock to an error code
   path in acpi_resume_power_resources().

 - Some code related to ACPI power resources, whose very purpose is
   questionable to put it lightly, turns out to cause problems to
   happen during testing on real systems, so remove it completely
   (we may revisit that in the future if there's a compelling enough
   reason).  From Rafael J Wysocki and Aaron Lu.
