Please split out the API change from the use of it in the PXA SSP driver
- just include enough to keep it building, then send a second patch
changing the internals of the SSP driver. At the minute there's two
different changes in here.

This is wrong, the WM9081 is a DAC only part so it should be paying
attention to the RX mask, not the TX one. We also need to handle the
sample size here.
I've not checked the SSP code yet.
