regulator: Fixes for v3.13

A bunch of fixes, a few driver specific ones and a framework fix for
voltage enumeration on fixed voltage regulators which had previously
worked but had been misplaced during some refactoring causing problems
for users that needed to know the voltage.

Linux 3.13-rc1

sound fixes #2 for 3.13-rc1

A collection of small fixes in HD-audio quirks and runtime PM, ASoC
rcar, abs8500 and other codecs.  Most of commits are for stable
kernels, too.

This is the 3.12.1 stable release

This is the 3.11.9 stable release

This is the 3.10.20 stable release

This is the 3.4.70 stable release

More ACPI and power management updates for 3.13-rc1

- ACPI-based device hotplug fixes for issues introduced recently and
  a fix for an older error code path bug in the ACPI PCI host bridge
  driver.

- Fix for recently broken OMAP cpufreq build from Viresh Kumar.

- Fix for a recent hibernation regression related to s2disk.

- Fix for a locking-related regression in the ACPI EC driver from
  Puneet Kumar.

- System suspend error code path fix related to runtime PM and
  runtime PM documentation update from Ulf Hansson.

- cpufreq's conservative governor fix from Xiaoguang Chen.

- New processor IDs for intel_idle and turbostat and removal of
  an obsolete Kconfig option from Len Brown.

- New device IDs for the ACPI LPSS (Low-Power Subsystem) driver and
  ACPI-based PCI hotplug (ACPIPHP) cleanup from Mika Westerberg.

- Removal of several ACPI video DMI blacklist entries that are not
  necessary any more from Aaron Lu.

- Rework of the ACPI companion representation in struct device and
  code cleanup related to that change from Rafael J Wysocki,
  Lan Tianyu and Jarkko Nikula.

- Fixes for assigning names to ACPI-enumerated I2C and SPI devices
  from Jarkko Nikula.

sound fixes for 3.13-rc1

Two peaks in diffstat are for the audio EQ init of IDT codecs and the
EMU2004 usb mixer addition, both of which are pretty device-specific,
so safe to apply.  The rest are a bunch of small fixes, most of them
are regression fixes.

IOMMU Updates for Linux v3.13

This time the updates contain:

* Tracepoints for certain IOMMU-API functions to make
  their use easier to debug
* A tracepoint for IOMMU page faults to make it easier
  to get them in user space
* Updates and fixes for the new ARM SMMU driver after
  the first hardware showed up
* Various other fixes and cleanups in other IOMMU drivers

Here are the 3.13 KVM changes.  There was a lot of work on the PPC
side: the HV and emulation flavors can now coexist in a single kernel
is probably the most interesting change from a user point of view.
On the x86 side there are nested virtualization improvements and a
few bugfixes.  ARM got transparent huge page support, improved
overcommit, and support for big endian guests.

Finally, there is a new interface to connect KVM with VFIO.  This
helps with devices that use NoSnoop PCI transactions, letting the
driver in the guest execute WBINVD instructions.  This includes
some nVidia cards on Windows, that fail to start without these
patches and the corresponding userspace changes.

fbdev changes for 3.13

Nothing particularly stands out in this pull request. The biggest part of the
changes are cleanups.

Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential
dead lock" which hopefully fixes the fb locking issues reported by multiple
persons.

There are also a few commits that have changes to arch/arm/mach-at91 and
arch/avr32, which have been acked by the maintainers.

This is the 3.11.8 stable release

This is the 3.10.19 stable release

This is the 3.4.69 stable release

DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.

- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
  prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
  multiple interrupt controllers.
- Refactoring of DT interrupt parsing code in preparation for deferred
  probe of interrupts.
- ARM cpu and cpu topology bindings documentation.
- Various DT vendor binding documentation updates.

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.
