[PATCH RFC v3 0/7] Implement generic ASoC HDMI codec and use it in tda998x

[Jyri Sarha <jsarha@ti.com>]

This is my third RFC patch series on the subject. This time also the
tda998x driver patches are a serious attempt to come up with an
initial implementation for HDMI audio ASoC support.

Russell's "drm/edid: add function to help find SADs" is here just to
produce a working patch-set on top of mainline. It should be getting in
trough drm-next at some point.

The binding for tda998x is taken from Jean Francois' patch series[1] on
the same subject. The implementation of the of-node parsing has some
minor changes from my self.

Here is what I think at least could or should still be done, but non of
that stuff does not sounds critical right now.
 
Missing from tda998x driver side
- hdmi_codec_ops audio_startup() implementation for audio abort support
- multi channel audio support (I would need specs and preferably some
  HW to test for this).

Missing from ASoC side generic implementation:
- channel_allocation handling is completely left for the video side driver,
  see if ASoC side could help in any way
- snd_soc_jack functionality to handle hdmi cable plug/unplug events
