[alsa-devel] [PATCH v8 0/9] adapt SOF to use snd-hda-codec-hdmi

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

Hey,
here's the 8th 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.

Intended to go in via Mark's ASoC tree.

v8 changes:
- rebased on top of Mark's for-next (50484b6a523a)
- addressed Takashi's review comment to patch 5
- addressed two sparse warnings in patch 3 reported by
  kbuild test robot <lkp@intel.com>
- fixed itnull.cocci warning in patch 3 reported by
  Julia Lawall <julia.lawall@lip6.fr> and
  kbuild test robot <lkp@intel.com>

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)
