The patches are based on linux 3.16-rc2 and OMAPDSS HDMI infoframe patches[1] from Tomi Valkeinen. The base, the patches, and couple of additional not-to-be-merged omap2plus_defconfig patches can be found here:

The patch set fixes OMAP4+ HDMI audio. The structure of the implementation looks a bit different than before. Instead of creating a driver specific API for a separate ASoC component driver to connect to, this implementation integrates an the ASoC cpu-dai component driver into the HDMI driver. Also the other ASoC component drivers needed for operational audio are automatically registered by the HDMI driver. There is no need to add anything to the device tree as long as the nodes needed for HDMI video are there.
Big part of the HDMI audio code is still unchanged and there is a need for a cleanup there. Also there is still probably something wrong with speaker mapping of multi-channel streams. I will get back to cleaning up these issues later.
Best regards, Jyri
