[alsa-devel] [PATCH v5 00/15] Rework OMAP4+ HDMI audio support

[Jyri Sarha]

The patches are based on:
git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git for-next

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

Changes since v4:
- Turn ASoC parts into a platform device driver
- Some cleaning up
- reorder the patches to keep bisect working

Changes since v3:
- Move ASoC parts into library module under sound/soc/omap
- Come up with API for the library 
- Some cleaning up

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, these patches implement a platform device driver under
sound/soc/omap for ASoC side implementation. This driver should only
be registered from OMAPDSS HDMI code. 

The ASoC side driver implements cpu-dai component using the callbacks
provided by OMAPDSS. Omap-pcm is registered for platform component,
dummy hdmi-audio-codec is registered for codec component, and
asoc-simple-card is registered for machine driver.

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
