sound updates for 5.5-rc1

There have been some significant changes in the core side, both for
ALSA and ASoC, while lots of development have been seen in SOF, as
well as many small fixes/improvements for ASoC codecs and platforms.
Below is a highlight in this cycle:

Core:
- The unification of PCM vmalloc buffer allocation helpers into the
  standard API
- Clean up of the default PCM mmap handling for vmalloc & SG-buffer
- Fix potential races at ALSA timer open
- A few new PCM API extensions; just preliminary core changes, the
  actual changes in drivers will be merged in 5.6
- Continued ASoC componentization works; now almost everything is a
  common ASoC component object.  A lot of refactoring and
  simplification have been done along with it.

ASoC:
- Many fixes to the Sound Open Firmware (SOF) code
- Wake on voice support for Chromebooks
- SPI support and trigger word detection for RT5677
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
  with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770

HD-audio:
- Improved Intel DSP configuration / probe code for SOF
- Plumbing the legacy HD-audio driver with Intel SOF HDMI
- DP-MST support for Nvidia HDMI codecs
- Realtek quirks cleanups and new additions as usual

Others:
- Lots of refactoring and cleanups for FireWire; period-size sharing,
  h/w IRQ interval configuration, clock recovery improvements, etc
- USB-audio: Scarlett mixer quirks
- Cleanups of PCM calls in various drivers (including media and USB)
  to adapt the core API changes

This is the 4.4.203 stable release

regulator: Updates for v5.5

Another fairly quiet release for the regulator API, some work all around
including some core work but mostly in specialist or driver specific
code:

 - Fix for powering off boot-on regulators.
 - Enhancements to the coupled regulator support introduced in the last
   release.
 - Conversion of a bunch of drivers to the fwnode API for GPIOs.
 - Mode support for DA9062.
 - New device support for Qualcomm PM1650, PM8004 and PM895 and Silergy
   SR83X.
 - Removal of obsolete AB8505 support.

ASoC: More updates for v5.5

Some more development work for v5.5.  Highlights include:

 - More cleanups from Morimoto-san.
 - Trigger word detection for RT5677.

This is the 4.9.203 stable release

Linux 5.4

This is the 4.14.156 stable release

This is the 4.19.86 stable release

This is the 5.3.13 stable release

drm-next-5.5-2019-11-22:

amdgpu:
- Fix bad DMA on some PPC platforms
- MMHUB fix for powergating
- BACO fix for Navi
- Misc raven fixes
- Enable vbios fetch directly from rom on navi
- debugfs fix for DC
- SR-IOV fixes for arcturus

wireless-drivers-next patches for v5.5

Last set of patches for v5.5. Major features here 802.11ax support for
qtnfmac and airtime fairness support to mt76. And naturally smaller
fixes and improvements all over.

Major changes:

qtnfmac

* add 802.11ax support in AP mode

* enable offload bridging support

iwlwifi

* support TX/RX antennas reporting

mt76

* mt7615 smart carrier sense support

* aggregation statistics via debugfs

* airtime fairness (ATF) support

* mt76x0 OF mac address support

This is the 3.16.78 stable release

The interesting new thing here is AQL, the Airtime Queue Limit
patchset from Kan Yan (Google) and Toke Høiland-Jørgensen (Redhat).
The effect is intended to eventually be similar to BQL, but byte
queue limits are not useful in wifi where the actual throughput can
vary by around 4 orders of magnitude. There are more details in the
patches themselves.

Power management regression fix for final 5.4

Fix problems with switching cpufreq drivers on some x86 systems with
ACPI (and with changing the operation modes of the intel_pstate driver
on those systems) introduced by recent changes related to the
management of frequency limits in cpufreq.
