[RFC v2 0/6] ASoC: Add mediatek HDMI codec support

[Philipp Zabel]

Hi,

this time we add an interface for Jyri's generic hdmi-codec driver [1] to
the mediatek hdmi bridge driver. In place of a separate machine driver,
the existing mt8173-rt5650-rt5676 driver is extended to link to the
hdmi-codec instance provided by the hdmi bridge driver.

The alsa jack support, previously implemented by the custom mediatek hdmi
codec and machine drivers, is bolted on top of hdmi-codec using Russell's
HDMI notifier prototype. It's all still a bit rough, but I could use some
feedback at this point. Have we achieved consensus to go forward with the
hdmi-codec approach? Is it ok to use an alsa jack for HDMI HPD status
reporting?

The mediatek drm patches apply on top of
https://patchwork.kernel.org/patch/7949021/ ("drm/mediatek: Add HDMI support")
the asoc patches depend on these two patches:
https://patchwork.kernel.org/patch/7215121/ ("ALSA: pcm: add IEC958 channel status helper for hw_params")
[1] https://patchwork.kernel.org/patch/7215271/ ("ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders")

best regards
Philipp
