Hi,
these patches add an interface for Jyri's generic hdmi-codec driver [1] to the mediatek hdmi bridge driver. The accesses to the hcp->eld field are now locked by a mutex, and I have added a patch to use the hdmi helper function [2] for N/CTS calculation.
Changes since v3: - Add mutex to lock hcp->eld - Use helper function for N and CTS calculation
The mediatek drm patches apply on top of https://patchwork.kernel.org/patch/8337071/ ("drm/mediatek: Add HDMI support"), and need this patch: [2] https://patchwork.kernel.org/patch/8091531/ ("video: hdmi: add helper function for N and CTS") 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")
regards Philipp
