ASoC: Further updates for v4.2

There's a bunch of additional updates and fixes that came in since my
orignal pull request here, including DT support for rt5645 and fairly
large serieses of cleanups and improvements to tas2552 and rcar.

This is the big bulk of GPIO changes queued for the v4.2
kernel series:

- A big set of cleanups to the aged sysfs interface from
  Johan Hovold. To get these in, v4.1-rc3 was merged into
  the tree as the first patch in that series had to go
  into stable. This makes the locking much more fine-grained
  (get rid of the "big GPIO lock(s)" and store states in the
  GPIO descriptors.

- Rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value()
  to avoid confusions.

- New drivers for:
  - NXP LPC18xx (currently LPC1850)
  - NetLogic XLP
  - Broadcom STB SoC's
  - Axis ETRAXFS
  - Zynq Ultrascale+ (subdriver)

- ACPI:
  - Make it possible to retrieve GpioInt resources from
    a GPIO device using acpi_dev_gpio_irq_get()
  - Merge some dependent I2C changes exploiting this.
  - Support the ARM X-Gene GPIO standby driver.

- Make it possible for the generic GPIO driver to read
  back the value set registers to reflect current
  status.

- Loads of OMAP IRQ handling fixes.

- Incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
  PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.

- Janitorial (contification, checkpatch cleanups)

Linux 4.1

- refactoring hpd irq handlers (Jani)
- polish skl dpll code a bit (Damien)
- dynamic cdclk adjustement (Ville & Mika)
- fix up 12bpc hdmi and enable it for real again (Ville)
- extend hsw cmd parser to be useful for atomic configuration (Franscico Jerez)
- even more atomic conversion and rolling state handling out across modeset code
  from Maarten & Ander
- fix DRRS idleness detection (Ramalingam)
- clean up dsp address alignment handling (Ville)
- some fbc cleanup patches from Paulo
- prevent hard-hangs when trying to reset the gpu on skl (Mika)

sound fixes for 4.1-final

Nothing looks scary, just a few usual HD-audio regression fixes
and fixup, in addition to a minor Kconfig dependency fix for
the old MIPS drivers.

This is the 3.4.108 stable release

Linaro 15.06

Major changes:

mwifiex:

* enhancements for AP mode: support verbose information in station
  dump command and also information about AP link.
* enable power save by default

brcmfmac:

* fix module reload issue for PCIe
* improving msgbuf protocol for PCIe devices
* rework .get_station() cfg80211 callback operation
* determine interface combinations upon device feature support

ath9k:

* ath9k_htc: add support of channel switch

wil6210:

* add modparam for bcast ring size
* support hidden SSID
* add per-MCS Rx stats

This is the 3.12.44 stable release

Linux 4.1-rc8

Allwinner clocks additions for 4.2

One error fix, and one patch to add support for the USB clock found on the
Allwinner A23 and A33

Linux 3.18.16

Linux 3.18.15

sound fixes for 4.1-rc8

Most of commits are regression fixes for HD-audio: a few corner case
fixes for regmap transition, and i915 binding issues.  In addition, a
quirk for another USB-audio device supporting DSD.

For this round we mostly have fixes:
 * mesh fixes from Alexis Green and Chun-Yeow Yeoh,
 * a documentation fix from Jakub Kicinski,
 * a missing channel release (from Michal Kazior),
 * a fix for a signal strength reporting bug (from Sara Sharon),
 * handle deauth while associating (myself),
 * don't report mangled TX SKB back to userspace for status (myself),
 * handle aggregation session timeouts properly in fast-xmit (myself)

However, there are also a few cleanups and one big change that
affects all drivers (and that required me to pull in your tree)
to change the mac80211 HW flags to use an unsigned long bitmap
so that we can extend them more easily - we're running out of
flags even with a cleanup to remove the two unused ones.

Third round of new IIO drivers, cleanups and functionality for the 4.2 cycle.

Given Linus announced a 4.8rc coming up, hopefully time for one more
lot of IIO patches this cycle.  Some of these are actually
improvements / fixes for patches earlier in the cycle.

New device support
* st_accel driver - support devices with 8 bit channels.

Cleanup
* A general cleanup of the iio tools under /tools/ from Hartmut.
  I'm more than a little embarassed by how bad some of these were! Are well,
  much more refined and less bug prone now.
  These cover lots of stuff like unhandled error returns, memory leaks as
  well as general refactoring to tidy the code up.
* iio_simple_dummy - fix memory leaks in the init functions, drop some
  pointless error returns from functions that never generate errors and
  make the module parameter explicitly unsigned.
* More buffer handling reworks from Lars-Peter, this time targetting hardware
  buffers (a little used corner that looks likely to get more use in the near
  future). Specifically:
  - Always compute the masklength as inkernel buffer users may need it.
  - Add a means of labeling which buffer modes a given buffer implementation
    supports.
  - In the case of hardware buffers, require strict scan matching rather than
    matching to a superset.  Currently the demux is bypassed by these drivers
    (this may well not change for efficiency reasons) so allowing a superset
    of channels to be selected would otherwise lead to more data than requested
    confusing userspace.

Driver funcationality improvments
* mmc35240 - adds a compensation to the raw values as borrowed form Memsic's
  own input driver.
* mma8452
  - event support
  - event debouncing
  - high  pass filter configuration
  - triggers
* vf610 - allow conversion mode to be adjusted

Fixlets
* mmc35240
  - Off by one error that by coincidence had no real effect.
  - i2c_device_name should be lowercase.
  - Lack of null terminator at end of attributes array.
  - Avoid computing the fractional part of the magnetic field by moving
    the scaling into userspace where floating point is available to simplify
    the maths.
  - Use a smaller sleep before assuming the measurement is done.  This is
    safe and improves the possible polling rate.
  - Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd
    code and the value used in the code seems to be correct.
* stk3310 - make a local variable signed to ensure error handling works.
* twl4030
  - fix calculation of the temperature sense current - bug unlikely
    to have ever been noticed as the difference is small.
  - Fix errors in descriptions.
