[alsa-devel] [PATCH v4 00/15] Rework OMAP4+ HDMI audio support
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 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

The OMAP5 HDMI audio implementation needs HDMI_AUDIO_LAYOUT_6CH in hdmi_core_audio_layout enum. I found the correct value from ti-linux 3.8 tree.

It does not waste too many bytes to compile all audio related core functions always in with HDMI support. It should help readability and in keeping the audio code in working shape. Leave the options just for disabling and enabling the functionality in hdmi[45].c.

Removes the OMAP5 HDMI audio callbacks for an external audio driver and the old external DAI driver does not work anymore after this patch.

In new model these callbacks are obsolete since the ASoC component drivers are integrated into the HDMI drivers and no callbacks are needed anymore.

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
