Linux 3.12

sound fixes #2 for 3.12-final

The fixes for random bugs that have been reported lately in the game:
a few fixes in ASoC dpam and wm_hubs bugs spotted by Coverity, a
one-liner HD-audio fixup, and a fix for Oops with DPCM.

They are not so critically urgent bugs, but all small and safe.

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

Fifth round of IIO new drivers, cleanups and functionality for the 3.13 cycle.

New Driver
* Freescale mag3110 magnetometer driver.

New functionality
* Add LPS001WP support to the ST pressure driver.
* Allow the max1363 driver to use only smbus functions for 8 bit devices. This
  allows the driver to be used when more extensive i2c support is not
  available.

Cleanups
* Fix incorrect description of unit conversions in ak8975.
* Switch to pr_err in industrialio-core.c instead of direct printk calls.
* Some simple redundant error handling removal patches.
* Trivial warning suppression by adding brackets to a sizeof call.
* Drop redundant of_match_ptr casts in drivers that are dependent on
  OF supporting being present.  The only purpose of the of_match_ptr
  wrapper was to make stubbing out of the relevant structures trivial.

Fixes
* Make MXS_LRADC depend on INPUT to avoid compile failures. This fixes an
  issue introduced in the previous pull in this cycle.

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.

This is the 3.4.67 stable release

This is the 3.0.101 stable release

Linux 3.12-rc6

Fourth round of IIO new drivers, functionality and cleanups for the 3.13 cycle.

New Drivers
* cm36651 combined RGB light and proximity sensor.

Core improvements

* Some more fixes and cleanups related to buffers.  These include the second
  half of a series which went is as fixes.  The basis for delaying until the
  next merge window is that some are too invasive for this late in a cycle
  and others only effect code paths current unused in the mainline tree.
  In this case we have:
   * protecting against concurrent userspace access
   * fixing a memory leak if a device goes away
   * avoiding always reallocating the buffer whether or not it has changed
     (a bug fix, but one with no functional changes other than a small speed
     improvement.)
   * Add reference counting for buffers to ensure they hang around if open
     from userspace or in kernel when the device is forcefully removed.
   * Return -ENODEV for buffer access operations when the device has gone
     away.
   * Add proper locking for iio_update_buffers (currently we only have one
     buffer per device in mainline, but an input bridge driver is under
     development which would make this bug 'real'.)
   * Wake up anyone waiting on a buffer if the device is unregistered.  A
     subsequent read will fail, notifying userspace that the device is no
     longer there rather than having it wait possibly for ever.

* Move the iio_sw_preenable functionality into the core.  This avoids drivers
  having to 'know' about how the buffers are implemented and is called by
  almost all drivers anyway.  Those that don't call it are not harmed by it
  being called.
* New registration approach for information (i.e. sysfs attributes) about
  events.  Much more generic and now similar to how the equivalent is
  handled for channel information.  The events infrastructure had been left
  behind by other changes so this brings it back in line.
* Using the new events registration approach, add a hysterisis event_info
  element and apply this to those drivers with this property.
* A little unitialized variable bug in the generic_buffer.c example.
* Factor out the code for freeing lists of IIO Device attributes to avoid
  some repitition.

Driver cleanups
* At91 driver gains touch screen support and some related fixes.
* Follow up series of patches removing the now redundant
  iio_sw_buffer_preenable calls.
* Lots of conversions to the new event registration methods.
* Another round of hmc5843 cleanups as that driver moves towards graduating
  from staging.
* Make some SoC drivers buildable if COMPILE_TEST is used.  Follow up fixes
  for a few bits and bobs that revealed.
* Add explicit includes of linux/of.h to those drivers making us of linux/of.h

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.

Allwinner sunXi SoCs minor fixes for 3.13

Allwinner sunXi SoCs device tree changes for 3.13

This DT series sees the introduction of the cubietruck DT, plus the addition of
the i2c controller for the A20 based boards, and of the Security ID found in
all the Allwinner SoCs but the A31.

Allwinner sunXi defconfig changes for 3.13

This pull request only see the introduction of a sunxi_defconfig.

Allwinner sunXi SoCs machine additions for 3.13

Nothing outstanding here, mostly some documentation cleanup, and the split of
the previous generic machine declaration into three different machines to
handle the sun4i/sun5i, sun6i and sun7i separately.

regulator: Allow supplies to be aliased

Provide an interface for devices to map their supplies elsewhere, mainly
for MFDs to handle their subdevices.
