regulator: Updates for v5.6

Hardly anything going on in the core this time around with the regulator
API and pretty quiet on the driver front:

 - An API for comparing regulators, useful for devices that need to
   check if supply voltages exactly match rather than just nominally
   match.
 - Conversion of several DT bindings to YAML format.
 - Conversion of I2C drivers to probe_new().
 - New drivers for Monolithic MPQ7920 and MP8859, and Rohm BD71828.

ASoC: Updates for v5.6

A pretty big release this time around, a lot of new drivers and both

   interfaces and moving things to the component level.
 - Transition of drivers to managed buffer allocation and removal of
   redundant PCM ioctls.
 - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
   WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
   and RT1308.

amd-drm-fixes-5.5-2020-01-23:

amdgpu:
- remove the experimental flag from renoir

Power management fix for 5.5-rc8

Prevent the kernel from crashing during resume from hibernation
if free pages contain leftover data from the restore kernel and
init_on_free is set (Alexander Potapenko).

wireless-drivers fixes for v5.5

Second set of fixes for v5.5. There are quite a few patches,
especially on iwlwifi, due to me being on a long break. Libertas also
has a security fix and mt76 a build fix.

iwlwifi

* don't send the PPAG command when PPAG is disabled, since it can cause problems

* a few fixes for a HW bug

* a fix for RS offload;

* a fix for 3168 devices where the NVM tables where the wrong tables were being read

* fix a couple of potential memory leaks in TXQ code

* disable L0S states in all hardware since our hardware doesn't
 officially support them anymore (and older versions of the hardware
 had instability in these states)

* remove lar_disable parameter since it has been causing issues for
  some people who erroneously disable it

* force the debug monitor HW to stop also when debug is disabled,
  since it sometimes stays on and prevents low system power states

* don't send IWL_MVM_RXQ_NSSN_SYNC notification due to DMA problems

libertas

* fix two buffer overflows

mt76

* build fix related to CONFIG_MT76_LEDS

* fix off by one in bitrates handling

This is the 5.4.14 stable release
