Linaro Debian 15.11

This is the 3.12.51 stable release

Linux 4.4-rc2

Second set of IIO fixes for the 4.4 cycle.

Some of these were waiting for various code to hit during the merge
window - others have simply shown up recently.

* Dummy - fix a bug introduced recently that stops events actually
  reaching userspace.
* Lidar - return -EINVAL on getting a report of an invalid reading from
  the device.  This could mean that nothing is in range, or something
  else has gone wrong.  Basically it tells us nothing useful beyond the
  reading is bogus and should be ignored.
* apds9660 - make sure to call pm_runtime_mark_last_busy when reading
  from the device to avoid a premature disabling of the power.
* core - fix up a few missues of the WARN macro.
* spmi-vadc - fix a missing of_node_put when breaking out of
  a for_each_available_child_of_node loop.

The dummy driver is going to result in a slightly interesting
merge when this meets the togreg branch as that driver has graduated
from staging in the meantime.  I'll send an email in reply to that
pull request highlighting this as well.

First set of new device support, features and cleanups for IIO in the 4.5 cycle

Usual mixed bag, but the big item perhaps in this series is the DMA buffer
support added by Lars-Peter Clausen. It's been in the works for a long time
and it will be interesting to see what hardware support shows up now that
this is available.

New core features + associate cleanup.
* Add generic DMA buffer infrastructure
* Add a DMAengine framework based buffer
 Also associated minor changes.
   - Set the device buffer watermark based on the minimum watermark for all
     attached buffers rather than just the 'primary' one.
   - iio_buffer_init - only set the watermark default if one hasn't already
     been provided.  This allows simple support for devices with a fixed
     watermark.
   - read only attribute for watermark on fixed watermark devices.
   - add explicit buffer enable/disable callbacks to allow the buffer to
     do more than trivial actions when it is being turned on and off.
* IIO_VAL_INT support in write_raw_get_fmt function.

New device support
* Freescale MMA7455/7456L accelerometers
* Memsic MXC6255XC accelerometer
* ST lis2dh12 accelerometer
* TI ADS8688 ADC
* TI Palamas (twl6035/7) gpadc

New driver features
* mma8452
  - support either of the available interrupt pins to cope with the case
    where board layout has lead to a particular one being connected.

Staging graduation
* Dummy driver
  - this driver acts as both an example and a test device for those with
    out hardware to develop userspace code against.

Cleanups and minor bits and bobs.
* treewide
  - Sort out the ordering of iio_device_register/unregister vs runtime
    pm function calls so that it's all nice and consistent and not race
    prone.
  - Check sscanf return values.  None of the cases will actually happen as
    the strings are supplied internally, but best to be consistent on this.
* ad7780
  - switch over to the gpio descriptor interface and remove the now unused
    platform data which gets rid of a header entirely.
* ad7793
  - drop a pointless else statement.
* at91_adc
  - Swap kmalloc_array in for a kmalloc doing the same job.
* dummy
  - get rid of some commented out lines that snuck in during the move of
    the driver.
* lm3533-als
  - Print an error message on provision of an invalid resistance.
* mcp320x
  - Add compatible strings with vendor prefix and deprecate those with
    no vendor prefix.
* mxs-lradc
  - Use BIT macro in various places rather than shifted ones.
* pa12203001
  - Power off the chip if the registration fails.
* pulsedlight-lidar-lite
  - add runtime PM support.
* xilinx XADC
  - constify an iio_buffer_setup_ops structure.

iwlwifi

* bump API to firmware 19 - not released yet.
* fix D3 flows (Luca)
* new device IDs (Oren)
* fix NULL pointer dereference (Avri)

ath10k

* fix invalid NSS for 4x4 devices
* add QCA9377 hw1.0 support
* fix QCA6174 regression with CE5 usage

wil6210

* new maintainer - Maya Erez

rtlwifi

* rtl8821ae: Fix lockups on boot

qcomlt-v4.3-rc5

This is the 3.2.73 stable release

Linux 4.4-rc1

First set of IIO fixes for the 4.4 cycle.

This set does not include those for issues introduced during the merge
window.  Fixes of those will follow in a future series.

* ad5064
  - Make sure the local i2c_write returns 0 on success rather than the
    number of bytes transfered.  Otherwise we report an error on all writes.
  - Fix a shift for ad5629 and ad5669 which gives incorrect DAC output on
    these parts.
* ad7793
  - The product ID on the datasheet is wrong.  Fix it in the driver.
* IIO_DUMMY_EVGEN
  - select IRQ_WORK as a dependency.
* lpc32xx
  - make sure clock is prepared before enabling.
* si7020
  - data byte order was reversed. Fix it.
* vf610
  - Internal temperature calculation was wrong if a different
    reference voltage was used.  Now use a linear interpolation
    function to make it work over the full range.
  - Fix a division by zero in the case of a device tree property
    not being present (same issue two fixes).
* xilinx XADC
  - VREFN scale was wrong - fix it.

sound fixes for 4.4-rc1

Here are a collection of small fixes tha have been gathered for
4.4-rc1.  The only significant changes are those in PCI drivers
Kconfig, to use "depends on" instead of "select" for CONFIG_ZONE_DMA.
A reverse select is often more user-friendly, but in this case, it
makes hard to manage with the conflict with ZONE_DEVICE, so changed in
such a way for now.

Others are all small fixes and quirks: an error check in soundcore
reigster_chrdev(), HD-audio HDMI/DP phantom jack fix, Intel Broxton DP
quirk, USB-audio DSD device quirk, some constifications, etc.

DeviceTree fixes for 4.4-rc1:

- Add empty of_translate_address needed for HiSilicon network driver.

- Fix alignment requirements for CMA regions in DT.

- Fix booting on PPC systems which can't do WARN() early.

- Rename ak4554 binding doc from .c to .txt.

This is the 4.2.6 stable release
