AFSX won't be used in DIT mode. The related pins are AHCLKX and
the data pins.

Channel size settings will be made at the end of
davinci_mcasp_hw_params() routine and thus overwrite frame
format settings made for DIT mode. This patch fixes this issue
by taking op_mode into account. Tested with official PSP 3.2
kernel and sii9022a HDMI transmitter.

For both, wrt a survived regression test :)

Thanks.

How do you make the test? Is it "doesn't break compilation" test? Or
do you have S/PDIF capable device?

No, I'm running the driver in IIS mode, with a codec attached to the I2S
lines. All I can do for now is test that your patches do not break my
environment. I can not test DIT.

O.K. I see. That is actually, what I wonted to know, if it doesn't break i2s.
