Firstly, am unable to apply this patch on top of sound-next for testing purposes.

I have 3 major comments in general

1> split the patch one for regmap and other for dma handling, its hard to review this long patch.

2> in general we should deal with range of dais supported for va, tx and rx macros, this patch seems to be just handling only 3 dai ids.

3> Also some details on why dma is handled differently in tx/rx, va dais when compared to other dais. Probably dt-bindings for that too.

naming of wcd is bit misleading, as VA has nothing to do with WCD. May be a better naming here would help.

On the other hand may be you can convert this to a swith case and include other dai-ids here, instead of adding is_cdc_dma_port().
