From: Yegor Yefremov <yegorslists@googlemail.com>
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.

v3: don't set mask in davinci_hw_dit_param()
v2: fix checkpatch.pl warnings

This last hunk doesn't apply to my tree. There are two lines at the
beginning of the function
/* Set the PDIR for Serialiser as output */
mcasp_set_bits(dev->base + DAVINCI_MCASP_PDIR_REG, AFSX);
which are from a very old commit (b67f4487). Do you have any other
commits in your tree?

I sent one of them an Fr and got Vaibhav's ACK today. Resending as series.

Ah, and when resending, please make sure to prefix your subject with
