[PATCH v2 00/20] ASoC: omap: Bind the omap-pcm platform driver to dai device

[PATCH v2 00/20] ASoC: omap: Bind the omap-pcm platform driver to dai device

[Peter Ujfalusi]

Hi,

Changes since v1:
- Add resource managed snd_soc_register_platform()
- Use snd_soc_dai_init_dma_data()
- omap-pcm is using the devm_snd_soc_register_platform()
- Patch for davinci-mcasp since Version4 is using omap-pcm

Cover letter from v1:

This should have been done a long time ago...
Add support for binding the omap-pcm platform to a dai device. IN this way we
can remove the 'omap-pcm-audio' platform device/driver need.
The change will also going to simplify cases when we boot with DT and we can use
the same node for cpu_dai and platform.

Regards,
Peter

[PATCH v2 02/20] ASoC: omap-pcm: Support for binding the platform driver to dai devices

[Peter Ujfalusi]

With the new calls it is going to be possible to bind the platform driver
to a dai device which makes it easier for us in a long run to handle DT
boots, and opens the possibility to move machine driver to generic simple
card.

Aargh, true. I don't have omap-hdmi available to build in my config since I do
not have display support enabled for omap4/omap5.

Will send a patch to fix it asap.

[PATCH v2 11/20] ASoC: omap-abe-twl6040: Use the cpu_dai node to specify the platform driver

[Peter Ujfalusi]

Now that the platform driver is registered with the cpu_dai's device we
can use the same node for it instead of the hardwired name.
We can also remove the cpu_dai_name and platform_name from the dai_link
struct since we only support DT boot on OMAP4/5
