media fixes for v4.7-rc7

ACPI fixes for v4.7

 - Fix a recent regression in the ACPI EC driver introduced by a fix
   of another problem that uncovered a latent code ordering issue in
   the driver (Lv Zheng).

 - Revert a recent ACPICA commit that attempted to address a lock
   ordering issue introduced by a previous fix, but caused Dell
   Precision 5510 to fail to boot, revert that previous fix too and
   finally revert the commit that caused the original problem (a
   deadlock in the ACPICA code) to happen (Rafael Wysocki).

regulator: Fix qcom-smd list voltage issues for msm8974

This commit looks like a cleanup but in fact by causing the core to go
down some simplified code paths for noop regulators it avoids a boot
time crash for msm8974 platforms which was introduced in v4.7.  It has
been in -next for a while, the issues in mainline for these platforms
weren't flagged up to me until yesterday (I think it took some time to
figure out what was going wrong).

This is the 4.4.15 stable release

This is the 4.6.4 stable release

- move sink crc support over to atomic state (Maarten)
- fix up async fbdev init ordering (Chris)
- fbc fixes from Paulo and Chris

Linux 4.7-rc7

regulator: Provide a branch for moderninzation of the PWM code

There's a new, improved PWM API which allows a lot of improvements in
the PWM regulator driver.  Since the bulk of the changes are in the PWM
API this is being managed in the PWM tree, merge pending regulator API
changes to allow this to be resolved more easily.

IOMMU Fixes for Linux v4.7-rc6

Two Fixes:

	* Intel VT-d fix for a suspend/resume issue, introduced with the
	  scalability improvements in this cycle.

	* AMD IOMMU fix for systems that have unity mappings defined. There was
	  a race where translation got enabled before the unity mappings were
	  in place. This issue was seen on some HP servers.

Final (hopefully) GPIO fixes for v4.7:
- Fix an oops on the Asus Eee PC 1201
- Revert a patch trying to split GPIO parsing and GPIO configuration
- Revert a too liberal compile testing thing

Power management fixes for v4.7-rc7

 - Fix a recent performance regression on Power systems (powernv
   and pseries) introduced by a core cpuidle commit that decreased
   the precision of the last_residency conversion from nano- to
   microseconds, which should not matter in theory, but turned out
   to play not-so-well with the special "snooze" idle state on Power
   (Shreyas B Prabhu).

 - Fix a crash during resume from hibernation on x86-64 caused by
   possible corruption of the kernel text part of page tables in the
   last phase of image restoration exposed by a security-related
   change during the 4.3 development cycle (Rafael Wysocki).

ACPI fixes for v4.7-rc7

 - Fix a lock ordering issue in ACPICA introduced by a recent commit
   that attempted to fix a deadlock in the dynamic table loading code
   which in turn appeared after changes related to the handling of
   module-level AML also made in this cycle (Lv Zheng).

 - Fix a recent regression in the ACPI IRQ management code that may
   cause PCI drivers to be unable to register an IRQ if that IRQ
   happens to be shared with a device on the ISA bus, like the
   parallel port, by reverting one commit entirely and restoring the
   previous behavior in two other places (Sinan Kaya).

 - Fix a recent regression in the ACPI AML debugger introduced by
   the commit that removed incorrect usage of IS_ERR_VALUE() from
   multiple places (Lv Zheng).

One more set of new features:
 * beacon report (for radio measurement) support in cfg80211/mac80211
 * hwsim: allow wmediumd in namespaces
 * mac80211: extend 160MHz workaround to CSA IEs
 * mesh: properly encrypt group-addressed privacy action frames
 * mesh: allow setting peer AID
 * first steps for MU-MIMO monitor mode
 * along with various other cleanups and improvements

Two more fixes:
 * handle allocation failures in new(ish) A-MSDU decapsulation
 * don't leak memory on nl80211 ACL parse errors

Qualcomm ARM Based Driver Updates for v4.8 Part 2

* Fix probe order issue in SCM
* Add missing qcom_scm_is_available() API

Third set of IIO new device support, features and cleanups for the 4.8 cycle.

New core features
- Selection of the clock source for IIO timestamps.  This is done per device
  as it makes little sense to have events in one timebase and data timestamped
  on another.  Biggest reason for this is that we currently use a clock
  source which is non monotonic which can result in 'interesting' data sets.
  (Includes export for get_monotonic_corse64 which Thomas Gleixner didn't mind
   in an earlier version.)
- MAINTAINERS add the git tree to the list for IIO.

New device support + a kind of indirect staging graduation.
* Broadcom iproc-static-adc
  - new driver
* mcp4531
  - support for MCP454x, MCP456x, MCP464x and MCP466x potentiometers
* mpu6050
  - support the IC20608 6 axis motion tracking device
* st-sensors
  - support the lis3l02dq + drop the lis3l02dq driver from staging.
  The general purpose driver is missing event support, but good to get
  rid of this driver which was rather long in the tooth.

New driver features
* ak8975
  - Add vid regulator support and refactor handling in general.
  - Allow a delay after enabling regulators.
  - Runtime and system PM.
* bmg160
  - filter frequency control support.
* bmp280
  - SPI device support.
  - EOC interrupt support for the BMP085
  - power management support.
  - supply regulator support.
  - reset gpio support
  - dt bindings for reset gpio and regulators.
  - of table to support device tree registration
* max1363
  - Device tree bindings.
* mcp4531
  - Device tree bindings.
* st-pressure
  - temperature channels as part of triggered buffer (previously not due
  probably to alignment issues - see below).
  - lps22hb open drain interrupt support.
  - lps22hb temperature channel support

Cleanups and reworkings.
* numerous ADC drivers
  - ensure the iio_dev->dev.of_node is set to the parent dev.of_node so
  as to allow client bindings to find the device.
* ak8975
  - Fix incorrect handling of missing regulator
  - make sure power is down and remove.
* bmp280
  - read the calibration data only once as it doesn't change.
* isl29125
  - Use a few macros to make code a touch more readable.
* mma8452
  - fix a memory leak on error.
  - drop an unecessary bit of return value handling.
* potentiometer kconfig
  - typo fix.
* st-pressure
  - drop some uninformative default assignments of elements of the channel
  array structure (aids readability).
* st-sensors
  - Harden interrupt handling considerably.  These are actually all using
  level interrupts, but at least two known boards have them wired to
  edge only interrupt chips.  Hence a slightly interesting bit of handling
  is needed in which we first allow for the easy option (level triggered) and
  secondly check the status registers before reenabling edge interrupts and
  fall back to a tight loop in the thread until we successfully clear the
  interrupt.  No harm is done if we never succeed in doing so.  It's an odd
  patch that has been through a lot of revisions to reach a consensus on how
  to handle what is basically broken hardware (which the previous defaults
  allowed to kind of work).
  - Fix alignment to defined storagebytes boundaries.
  - Ensure alignment of power of 2 byte boundaries.  This has always in theory
  been part of the ABI of IIO, but we missed a few that snuck in that need
  fixing.  The effect was minor as they were only followed by timestamp
  channels which were correctly aligned,
  - Add some docs to explain the gain calculations.

Allwinner DT changes for 4.8

The usual amount of DT patches, among which:
  - I2S support
  - Support for the AXP809 in the relevant boards (A80 based)
  - New boards: Banapi M1+, Banapi M2+, Allwinner Parrot (R16 EVB),
  - The other patches to enable various controllers on our boards, most
    notably USB OTG

Allwinner defconfig changes for 4.8

Two patches to enable the DRM driver in the sunxi and multi_v7 defconfig.

Allwinner DRM driver fixes for 4.7, take 2

A new set of fixes for the sun4i driver, mostly related to vblank handling,
and a minor fix to release a reference on the device tree nodes we're
parsing in the probe logic.
