Is this assuming a 1:1 relationship between the serial port and the
MCLK? That's not going to be true for all systems. This definition
does feel a bit specific to the SSP (or I guess just general serial
ports used for audio as opposed to fixed function I2S/PCM controllers).
I don't know if it's worth splitting up though.

Better go for 640K to be sure :) ...

...more seriously I do notice a bunch of these FIXME and TODO comments
in here, given that it's an ABI it seems like those all need sorting
before things are merged. In this case perhaps just delete the HDA
stuff until someone works out what to do?
