So WRT the CS42888, this is one device in a series of 2 devices that are 
register compatible with the only difference being that the CS42488 has 2 
extra ADC's. Same die and same DeviceID.

Would it make more sense to submit the driver with the extra ADC's to make 
it feature complete for both devices? Wouldn't be odd to have 2 drivers 
that do the same for 98% of the code.
