Subject: [PATCH v3 0/5] MT8192 Asurada devicetree - Part 2


This series improves some more the support for MT8192 Asurada-based
Chromebooks, by enabling some missing functionality, namely the internal
display and audio.

In addition to that, aliases are also added for the i2c and mmc nodes,
which should've been done while adding the devices in the previous
series.

Some notable components that are still missing support are:
- external display/HDMI audio (waiting for [1])
- GPU (waiting for [2])

As part of testing the audio, an UCM file was used, which has already
been submitted upstream [3].

This series depends on some missing dt-binding properties on rt5682,
which are added by another series [4].

v1: https://lore.kernel.org/all/20220908171153.670762-1-nfraprado@collabora.com/

Changes in v3:
- Moved codec and sound card compatibles to separate dtsi to prepare for
  headset codec differences in newer revisions
- Added new supplies for rt5682
- Removed i2c aliases for unused controllers

Changes in v2:
- Extended series to also include patches 4 and 5 enabling audio and
  adding aliases
- Adjusted display regulator hierarchy and voltages to reflect the
  hardware
