Rework OMAP4+ HDMI audio support
v7 cover 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:
https://github.com/jsarha/linux.git omap-hdmi-audio
It would make the most sense to get these in trough fbdev tree. So it would be nice to get acked-bys (if the patches are Ok) for ASoC side changes from appropriate maintainers.
Changes since v6:
- "ASoC: omap-hdmi-audio: Add platform device for OMAP HDMI audio support"
- Fix Kconfig help text
- Remove #include <sound/simple_card.h>
- Use snd-soc-dummy codec instead of hdmi-audio-codec
- Add: OMAPDSS: hdmi_wp: Protect reserved bits in hdmi_wp_audio_config_format()
- Add: OMAPDSS: hdmi5_core: Initialize mandatory sample_order parameter
- Add: "OMAPDSS: omapdss.h: Remove audio_state member of struct omap_dss_device"
- "OMAPDSS: hdmi4: Register ASoC platform device for omap hdmi audio"
- Register "omap-hdmi-audio" with PLATFORM_DEVID_AUTO
- "OMAPDSS: hdmi5: Register ASoC platform device for omap hdmi audio"
- Register "omap-hdmi-audio" with PLATFORM_DEVID_AUTO
- Add: "OMAPDSS: hdmi5: Change hdmi_wp idlemode to to no_idle for audio playback"

In reply to Jyri SarhaThe platform device should only be registered from OMAPDSS HDMI driver. The platform driver registers and unregisters all ASoC components needed for OMAP HDMI audio.
The hdmi audio driver implements cpu-dai component using the callbacks provided by OMAPDSS and registers the component under DSS HDMI device. Omap-pcm is registered for platform component also under DSS HDMI device. Dummy codec is used as as codec component. The hdmi audio driver implements also the card and registers it under its own platform device.

Re: [PATCH v7 10/20] ASoC: omap-hdmi-audio: Add platform device for OMAP HDMI audio support
Quoted 4 lines · Jyri Sarha
The platform device should only be registered from OMAPDSS HDMI driver. The platform driver registers and unregisters all ASoC components needed for OMAP HDMI audio.
Quoted 8 lines
The hdmi audio driver implements cpu-dai component using the callbacks provided by OMAPDSS and registers the component under DSS HDMI device. Omap-pcm is registered for platform component also under DSS HDMI device. Dummy codec is used as as codec component. The hdmi audio driver implements also the card and registers it under its own platform device.
