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.

More power management and ACPI updates for v4.4-rc2

 - Revert three recent intel_pstate driver commits one of which
   introduced a regression and the remaining two depend on the
   problematic one (Rafael Wysocki).

 - Fix breakage related to the recently introduced ACPI _CCA object
   support in the PCI DMA setup code (Suravee Suthikulpanit).

 - Fix up the recently introduced ACPI CPPC support to only
   use the hardware-reduced version of the PCCT structure as
   the only architecture to support it (ARM64) will only use
   hardware-reduced ACPI anyway (Ashwin Chaugule).

 - Fix a cpufreq mediatek driver build problem (Arnd Bergmann).

 - Fix the SMBus transaction handling implementation in the ACPI
   core to avoid re-entrant calls to wait_event_timeout() which
   makes intermittent boot stalls related to the Smart Battery
   Subsystem initialization go away and revert a workaround of
   another problem with the same underlying root cause (Chris
   Bainbridge).

 - Fix the generic wakeup interrupts framework to avoid using
   invalid IRQ numbers (Dmitry Torokhov).

 - Remove a redundant check from the ACPI EC driver (Markus Elfring).

 - Modify the intel_pstate driver so it can support more Atom flavors
   than just one (Baytrail) and add support for Atom Airmont cores
   (which require new freqnency tables) to it (Philippe Longepe).

 - Clean up MSR-related symbols in turbostat (Len Brown).

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.

More power management and ACPI updates for v4.4-rc1

 - Support for the ACPI _CCA configuration object intended to tell
   the OS whether or not a bus master device supports hardware
   managed cache coherency and a new set of functions to allow
   drivers to check the cache coherency support for devices in a
   platform firmware interface agnostic way (Suravee Suthikulpanit,
   Jeremy Linton).

 - ACPI backlight quirks for ESPRIMO Mobile M9410 and Dell XPS L421X
   (Aaron Lu, Hans de Goede).

 - Fixes for the arm_big_little and s5pv210-cpufreq cpufreq drivers
   (Jon Medhurst, Nicolas Pitre).

 - kfree()-related fixup for the recently introduced CPPC cpufreq
   frontend (Markus Elfring).

 - intel_pstate fix reducing kernel log noise on systems where
   P-states are managed by hardware (Prarit Bhargava).

 - intel_pstate maintainers information update (Srinivas Pandruvada).

 - cpufreq core optimization related to the handling of delayed work
   items used by governors (Viresh Kumar).

 - Locking fixes and cleanups of the Operating Performance Points
   (OPP) framework (Viresh Kumar).

 - Generic power domains framework cleanups (Lina Iyer).

 - cpupower tool updates (Jacob Tanenbaum, Sriram Raghunathan,
   Thomas Renninger).

 - turbostat tool updates (Len Brown).

sound updates for 4.4-rc1

Here is the first batch of updates for sound system on 4.4-rc1.
Again at this time, the update looks fairly calm; no big changes in
either ALSA core or ASoC infrastructures, rather all small cleanups,
in addition to the new stuff as usual.

The biggest changes are about Firewire sound devices.  It gained lots
of new device support, and MIDI functionality.  Also there are updates
for a few still working-in-progress stuff (topology API and ASoC
skylake), too.  But overall, this update should give no big surprise.

Some highlight is below:

Core:
 - A few more Kconfig items for tinification; it's marked as EXPERT,
   so normal user should't be bothered :)
 - Refactoring with a new PCM hw_constraint helper
 - Removal of unused transfer_ack_{begin,end} PCM callbacks

Firewire:
 - Restructuring of code subtree, lots of refactoring
 - Support AMDTP variants
 - New driver for Digidesign 002/003 family
 - Adds support for TASCAM FireOne to ALSA OXFW driver
 - Add MIDI support to TASCAM and Digi00x devices

HD-Audio:
 - Automated modalias generation for codec drivers, finally
 - Improvement on heuristics for setting mixer name
 - A few fixes for longstanding bugs on Creative CA0132 cards
 - Addition of audio rate callback with i915 communication
 - Fix suspend issue on recent Dell XPS
 - Intel Lewisburg controller support

ASoC:
 - Updates to the topology userspace interface
 - Big updates to the Renesas support (rcar)
 - More updates for supporting Intel Sky Lake systems
 - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
   Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip
   S/PDIF, and Atmel class D amplifier

USB-Audio:
 - A fix for newer Roland MIDI devices
 - Quirks and workarounds for Zoom R16/24 device

Misc:
 - A few fixes for some old Cirrus CS46xx PCI sound boards
 - Yet another fixes for some old ESS Maestro3 PCI sound boards
