media updates for v5.4-rc1

media fixes for v5.3-rc9

sound updates for 5.4

As shown in diffstat and logs, it was again a busy development
cycle at this time, too.  The most significant changes are still
on-going refactoring / modernization works for ASoC core and
drivers, but there are lots of other changes as well.  Here we go,
some highlights below:

ASoC:
- Quite lots of cleanup / refactoring of ASoC core and APIs;
  most of them are systematic, but also including cleanups and
  modernization

- A bulk of updates for some ASoC platforms, Freescale, sunxi and
  Intel SST/SOF

- Initial support for Sound Open Firmware on i.MX8

- Removal of deprecated w90x900 and nuc900 drivers

- New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
  7ULP and 8MQ, Meson G12A and NXP UDA1334

USB-audio:
- More validations of descriptor units for hardening against bugs
  reported by fuzzers

- PCM device assignment workaround for a past call-order change

- Scarlett Gen2 mixer interface, a few more more quirks

HD-audio:
- Support for audio component with AMD/ATI and Nvidia HDMI codecs

- Clean up HD-audio core and remove indirect access ops for Intel SOF

- DMIC detection at probe; it would make systems automatically falling
  back to SST/SOF driver on devices that need DMIC handling.
  Needs a new Kconfig to set, and beware that it's still new and a bit
  experimental

FireWire:
- Lots of code refactoring and cleanups

This is the 5.2.15 stable release

This is the 4.19.73 stable release

This is the 4.14.144 stable release

This is the 4.9.193 stable release

This is the 4.4.193 stable release

regulator: Updates for v5.4

A small update for the regualtor API for this cycle, some small fixes
and a bunch of new devices but none of them very big.  The most stand
out thing is the regulator-fixed-clock driver which is for regulators
where the enable control is done by using a clock instead of a GPIO or
register write, a novel hardware design that had not previously come up.

 - Added a keyword pattern for regulator_get_optional() since usage of
   that API generally needs extra review.
 - Operating mode and suspend state support for act8865.
 - New device support for Active Semiconductor ACT8600 chargers,
   Mediatek MT6358, Qualcomm SM8150, regulator-fixed-clock, and
   Synoptics SY20276, SY20278 and SY8824E.

ASoC: Final merge window fixes for v5.4

A few small fixes and one feature that came in since I sent you the
earlier pull request.

Linux 5.3

wireless-drivers-next patches for 5.4

Last set of patches for 5.4. wil6210 and rtw88 being most active this
time, but ath9k also having a new module to load devices without
EEPROM.

Major changes:

wil6210

* add support for Enhanced Directional Multi-Gigabit (EDMG) channels 9-11

* add debugfs file to show PCM ring content

* report boottime_ns in scan results

ath9k

* add a separate loader for AR92XX (and older) pci(e) without eeprom

brcmfmac

* use the same wiphy after PCIe reset to not confuse the user space

rtw88

* enable interrupt migration

* enable AMSDU in AMPDU aggregation

* report RX power for each antenna

* enable to DPK and IQK calibration methods to improve performance

We have a number of changes, but things are settling down:
 * a fix in the new 6 GHz channel support
 * a fix for recent minstrel (rate control) updates
   for an infinite loop
 * handle interface type changes better wrt. management frame
   registrations (for management frames sent to userspace)
 * add in-BSS RX time to survey information
 * handle HW rfkill properly if !CONFIG_RFKILL
 * send deauth on IBSS station expiry, to avoid state mismatches
 * handle deferred crypto tailroom updates in mac80211 better
   when device restart happens
 * fix a spectre-v1 - really a continuation of a previous patch
 * advertise NL80211_CMD_UPDATE_FT_IES as supported if so
 * add some missing parsing in VHT extended NSS support
 * support HE in mac80211_hwsim
 * let mac80211 drivers determine the max MTU themselves
along with the usual cleanups etc.

ASoC: Updates for v5.4

Quite a big update this time around, particularly in the core
where we've had a lot of cleanups from Morimoto-san - there's
not much functional change but quite a bit of modernization
going on.  We've also seen a lot of driver work, a lot of it
cleanups but also some particular drivers.

 - Lots and lots of cleanups from Morimoto-san and Yue Haibing.
 - Lots of cleanups and enhancements to the Freescale, sunxi dnd
   Intel rivers.
 - Initial Sound Open Firmware suppot for i.MX8.
 - Removal of w90x900 and nuc900 drivers as the platforms are
   being removed.
 - New support for Cirrus Logic CS47L15 and CS47L92, Freescale
   i.MX 7ULP and 8MQ, Meson G12A and NXP UDA1334

This is the 5.2.14 stable release

This is the 4.19.72 stable release

This is the 4.14.143 stable release

This is the 4.9.192 stable release
