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
