After discussing with Tomi we decided to turn the omap-hdmi-audio ASoC library into a platform device. So do not waste too much time in reviewing these patches. I'll mail a new series soon.
Best regards, Jyri

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 single audio library module under sound/soc/omap for ASoC side implementation. The library exports omap_hdmi_audio_register() and omap_hdmi_audio_unregister() functions. With the functions OMAPDSS HDMI implementation registers and unregisters all ASoC components needed for OMAP HDMI audio.
The library 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
