[alsa-devel] [PATCH v4 0/9] adapt SOF to use snd-hda-codec-hdmi

[Kai Vehmanen <kai.vehmanen@linux.intel.com>]

Hi all,

here's the 4th 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.

v4 changes:
- Change order of patches to not break bisect (Pierre's feedback).
- Improve the explanation in commit message for
  mst_no_extra_pcms, patch 1. (Pierre's feedback).
- Fix errors in PCM constraints for HDMI (Pierre's feedback).
- Fix an issue on Ice Lake platforms (patch 3).

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)
