Hey,
here's the 5th round for this series that adapts SOF to use
snd-hda-codec-hdmi (patch_hdmi.c) codec driver instead of hdac_hdmi
(soc/codecs/hdac_hdmi.c). The primary goal is to unify the HDMI codec
implementation between DSP and non-DSP HDA configurations, offer same
interface to user-space and reduce maintenance load for all.
v5 changes:
- Fixed a bug with codec power management at probe. To imitate snd_hda_intel
driver, SOF needs to enable display power when doing codec probe
for HDMI codecs. Affects patches 2 and 5.
Feature and testing info:
- Tested on multiple Intel platforms supported by SOF.
- Tested with ALSA console tools as well as with Pulseaudio.
- requires Pulseaudio 12.x or newer, see
https://lists.freedesktop.org/archives/pulseaudio-discuss/2019-August/031358.html
- HDMI, DP, DP-MST with multi-monitor use-scenarios work ok.
- New feature for SOF: ELD /proc fs works just like in
DSP-less mode.
- New feature for SOF: jack detection works out-of-the-box
with Pulseaudio (no need for card specific UCM for HDMI)
