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
