[alsa-devel] [RFC v3 0/7] ASoC: Add mediatek HDMI codec support

[Philipp Zabel]

Hi,

these patches add an interface for Jyri's generic hdmi-codec driver [1] to
the mediatek hdmi bridge driver. I have added an initial connector status
event, made the hdmi bridge driver reuse the hdmi_codec_params that include
the IEC958 channel state, included a fix to allow playback while HDMI is not
connected, and added an ELD mixer control to the hdmi-codec driver.

The mediatek drm patches apply on top of
https://patchwork.kernel.org/patch/8018331/ ("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")

Changes since v2:
 - Pass down and reuse hdmi_codec_params, including the IEC958
   channel state.
 - Fixed hw_params not to fail when no hdmi cable is connected
 - Send an initial notification to set the correct jack state
 - Don't call get_eld, copy the ELD contained in the hdmi_event instead
 - Add an ELD control to the hdmi-codec driver
