[alsa-devel] [PATCH 1/2] ASoC: pcm1792a: Remove empty capture DAI stub
From: Mark Brown broonie@linaro.org
These intialisations are just what will be done for static data anyway so remove them.

Provide DAPM for the device, ensuring operation with DAPM required by the core and making it easier to hook up external hardware to it.

I'm working on support pcm1795 and pcm1796 too. They are registers compatible but different sample rate support. So the idea is three patches?
- rename pcm1792a to pcm179x (is it possible?) - add three different dai for pcm1792a, pcm1795 and pcm1796 - use of_device_id data pointer to select the correct dai

Yes, that seems like a good approach - no problem with the rename, just make sure the existing users are updated.
