That's not a general requirement of I2S - many devices are OK with
scaling the number of bit clocks with the data.

I'd go so far as to say that most of the testing has been in I2S mode.
Other modes have been tested but most of the usage is with I2S.

I suspect that what you need to do here to interoperate well with your
codec is to set things up to use TDM so that the extra clocks are
generated by what the CPU believes are idle TDM slots.

When submitting patches please do try to submit separate patches for
separate logical changes - for example, your previous patch mixed in
changes for recent PXA APIs with changes in the behaviour of the code.
