(This series depends on https://lore.kernel.org/patchwork/patch/1126819/ which has not applied to the maintainer's tree yet.)
This series makes mt8183-mt6358-ts3a227-max98357 support DP (display port) audio output.
ASoC: hdmi-codec: add PCM trigger operator - add a PCM trigger callback if codec driver is interested in PCM events.
drm: bridge: it6505: bridge to hdmi-codec - add audio feature support of it6505. - bridge to hdmi-codec so that ASoC can use the audio feature. - defer the "enabling" after receiving PCM START or RESUME event.
ASoC: dt-bindings: mt8183: add a property "mediatek,hdmi-codec" ASoC: mediatek: mt8183: use hdmi-codec - bind to hdmi-codec in mt8183-mt6358-ts3a227-max98357.
drm: bridge: it6505: report connector status ASoC: mediatek: mt8183: support HDMI jack reporting - use the mechanism from the following patch https://mailman.alsa-project.org/pipermail/alsa-devel/2019-September/155302.... to report jack status (from DRM to ASoC).

Hi Tzung-Bi,
We would want to confirm with you as we work on the hdmi-codec for the mt8186.
Do you have any plan to continue working on this series? We may take over as well.
Thanks, Allen

No (from testing's perspective). Please take over it as you require.

Bridge to hdmi-codec to support audio feature.
It is observed that some DP-to-HDMI dongles will get into bad states if sending InfoFrame without audio data. Defer to enable it6505's audio feature when PCM triggers START or RESUME.
