media fixes for v4.6-rc2

Linux 4.1.21

Linux 3.18.30

First round of IIO new device support, features and cleanups for the 4.7 cycle.

New core support
* UV light modifier (for intensity)
* UV light index channel type.

New device support
* hp206c barometer and altimeter
  - new driver.
* mcp4131 potentiometer
  - new driver supporting lots of parts from Microchip.
* mma8452
  - FXLS8471Q support
- NXP LPC18XX SOC ADC
  - new driver.
- NXP LPC18XX SOC DAC
  - new driver.
- rockchip_saradc
  - support rk3399
* st accel
  - h3lis331dl support

Staging driver removals
* adis16204
  - obsolete part making it hard to get parts to test the driver in order
    to clean it up.
* adis16220
  - obsolete part making it hard to get the parts test the driver in order
    to clean it up.

Features
* core
  - convenience functions to claim / release direct access to the device.
    Makes more consistent handling of this corner easier. Used in ad7192 driver.
* ak8975
  - power regulator support.
* at91-sama5d2
  - differential channel support.
* mma8452
  - runtime pm support
  - drop device specific autosleep and use the runtime pm one instead.
* ms5611
  - DT bindings
  - oversampling ratio support

Cleanups and minor fixes
* MAINTAINERS
  - Peter got married - hence name change!

* Documentation
  - Fix a typo in in_proximity_raw description.
  - Add some missing docs for iio_buffer_access_funcs.

* Tools
  - update iio_event_monitor names to match new stuff.
  - make generic_buffer look for triggers ending in -trigger as we let these in
  for a number of drivers a long time back and now it is a fairly common
  option.

Drivers
* staging wide
  - convert bare unsigned usage to unsigned int to comply with coding style.
* non staging wide:
  - since boiler plate gpio handling of interrupts has been moved into the
   ACPI core we don't need to include gpio/consumer.h in a load of drivers so
   drop it.
* ad7606
  - fix an endian casting sparse warning.
* ak8975
  - fix a possible unitialized warning from gcc.
  - drop and unused field left over from earlier cleanups
  - fix a missing regulator_disable on exit.
* at91-sama5d2
  - typo and indentation
  - missing IOMEM dependency.
  - cleanup mode register usage by avoidling erasing whole thing when changing
  the sampling frequency.
* bmc150
  - use the core demux and available_scan_masks to simplify buffer handling
  - optimize the transfers in the trigger handler now we have a magic function
  to emulate bulk reads (under circumstances met here).  This matters with some
  rather dumb i2c adapters in particular.
  - use a single regmap_conf for all bus types as they were all the same.
* bmg160
  - use the core demux and available_scan_masks to simplify the buffer handling
  - optimize the transfers in the trigger handler now we have a magic funciton
  to emulate bulk rads (under circumstances met here).
  - drop gpio interrupt probing from the driver (ACPI) as now handled by the
  ACPI core.
* ina2xx-adc
  - update the CALIB register when RShunt changes.
  - fix scale for VShunt - in reality this error canceled out when used.
* isl29028
  - use regmap to retrieve the struct device instead of carrying a second
  copy of it around.
* kxcjk-1013
  - use core demux
  - optimize i2c transfers in the trigger handler.
* mcp4531
  - refactor to use a pointer to access model parameters instead of indexing
    into the array each time.
* mma8452
  - style fixes
  - avoid swtiching to active whenever the config changes
  - add missin i2c_device_id for mma8451
* mpu6050
  - fix possible NULL dereference.
  - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
  - fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
  - drop gpio interrupt handling for ACPI case from driver as the core now
  handles this case.
* st-sensors
  - note that there are only ever a maximum of 3 axis on current st-sensors
  so just allocate a fixed sized buffer big enough for that.
* tpl0102
  - change the i2c_check_functionality condition to bring it inline with other
    IIO users as EOPNOTSUPP.
* tsl2563
  - replace deprecated flush_scheduled_work

Second set of IIO fixes for the 4.6 cycle.

This lot are either dependent on patches from the merge window or just came
in recently enough that they ended up in this tree.

* core
  - The watermark for the buffers was given a value that meant that it was
    impossible to actually set the watermark to anything sensible.
* at91_adc
  - Fix a build config dependency on HAS_IOMEM
* bmc150
  - Fix wrong output on big endian systems
* bmg160
  - Fix wrong output on big endian systems
  - Fix an issue in which the regmap return value was stored to the buffer
    rather than the value actually being read in a bulk read.
* inv_mpu6050
  - Fix an indirect build config dependency on HAS_IOMEM
* max30100
  - Fix an error in fifo check condition that leads to a double read of the
    final reading.
* st_magn
  - Make sure ST_MAGN_TRIGGER_SET_STATE is always defined to avoid a build
    error for relatively obscure config combinations.

First round of IIO fixes for the 4.6 cycle.

Again I've ended up with two early fix sets, depending on whether they are
dependent on elements of the merge window or simply came in after I had
patches with that dependency already, vs older fixes that were just too
late for the last cycle.  This first set is for the older ones.

- max1353
  * Add a missing adc to max1363_id - the driver has supported the
    max11644-11647 for a while, but as they weren't in the id table there
    was no way of actually initializing it.
  * Fix a wrong reference voltage for the above models.  Given you couldn't
    initialize the driver for these parts without patching, no one noticed
    that the reference voltage used in computing the scaling was wrong.
 - apds9960
   * The fifo last enelement was read twice (and hence pushed out twice) due
     to a small logic bug.

Linux 4.6-rc2

Qualcomm Fixes for v4.6-rc2

* Revert BAM usage on MSM8974 boards

Power management and ACPI material for v4.6-rc2

Just one fix for a nasty boot failure on some systems based on
Intel Skylake that shipped with broken firmware where enabling
hardware-coordinated P-states management (HWP) causes a faulty
interrupt handler in SMM to be invoked and crash the system
(Srinivas Pandruvada).

Linux 4.6-rc1

Power management and ACPI material for v4.6-rc1, part 2

 - Fix for an intel_pstate driver issue related to the handling of
   MSR updates uncovered by the recent cpufreq rework (Rafael Wysocki).

 - cpufreq core cleanups related to starting governors and frequency
   synchronization during resume from system suspend and a locking
   fix for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).

 - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
   Michael Neuling, Richard Cochran, Shilpasri Bhat).

 - intel_idle driver update preventing some Skylake-H systems
   from hanging during initialization by disabling deep C-states
   mishandled by the platform in the problematic configurations (Len
   Brown).

 - Intel Xeon Phi Processor x200 support for intel_idle (Dasaratharaman
   Chandramouli).

 - cpuidle menu governor updates to make it always honor PM QoS
   latency constraints (and prevent C1 from being used as the
   fallback C-state on x86 when they are set below its exit latency)
   and to restore the previous behavior to fall back to C1 if the next
   timer event is set far enough in the future that was changed in 4.4
   which led to an energy consumption regression (Rik van Riel, Rafael
   Wysocki).

 - New device ID for a future AMD UART controller in the ACPI driver
   for AMD SoCs (Wang Hongcheng).

 - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
   scaling (AVS) driver (David Wu).

 - ACPI PCI resources management fix for the handling of IO space
   resources on architectures where the IO space is memory mapped
   (IA64 and ARM64) broken by the introduction of common ACPI
   resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).

 - Fix for the ACPI backend of the generic device properties API
   to make it parse non-device (data node only) children of an
   ACPI device correctly (Irina Tirdea).

 - Fixes for the handling of global suspend flags (introduced in 4.4)
   during hibernation and resume from it (Lukas Wunner).

 - Support for obtaining configuration information from Device Trees
   in the PM clocks framework (Jon Hunter).

 - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
   King, Geert Uytterhoeven).

sound fixes for 4.6-rc1

The previous pull request introduced a few WARN_ON() for Intel
HD-audio HDMI.  Indeed it caught bugs, and now users get annoyed.
So this request came up: a collection of small fixes to paper over
the inconsistencies on (mostly) old Intel chipsets.

In addition, a trivial USB-audio quirk is included, too.
