Prakash,

The series looks good to me. I tested it again on DA850 EVM (with and
without DT).

I should have mentioned this previously, but your choice of name here is
too long. You can simply use dm355-mmc (rather dm6441-mmc?) and
da830-mmc instead like you did for SPI. This would have saved some long
lines. Sorry about not asking for this earlier. I know it would have
saved you a bunch of effort.

Thanks,
Sekhar
