[alsa-devel] [PATCH 00/12] Rework OMAP4+ HDMI audio support

[Jyri Sarha]

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:

git://git.ti.com/~jyrisarha/ti-linux-kernel/jyrisarhas-audio-video-linux-feature-tree.git omap-hdmi-audio

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
