Right now ASoC expects you to specify a DAI link for a PCM device. The DAI link connects the DAIs of two components typically the SoC side and a external CODEC. In your case you do not have the external CODEC. You can solve this by using a dummy CODEC or splitting things up and register both the CODEC and the CPU DAI from the same driver.
That would probably be the best solution, yes.
But I'm currently working on a patchset that will eventually allow these kind of devices to be supported more naturally. It will allow to register them as one component that won't need the CODEC component to work.
Great! Do you have a branch with that work somewhere?
Not yet. But I hope to get there in the next weeks.
Could you put me in Cc whenever you post them for feedback/testing?
Sure. I just had a quick peek at the datasheet and I think you should be able to get away with implementing this as a CODEC driver for now and use the dummy-dai for the CPU side in you DAI link.
