Can't we move these further up, so that next time we want to add
something it doesn't require that we also move the ENC/DEC bits?
Yes I will change it to BIT(30) and BIT(31)

While leaving room for the typical macro issues, none of the other
macros wrap the argument in parenthesis. Please follow the style of the
driver, and perhaps follow up with a cleanup patch that just wraps them
all in parenthesis?
This does throw up a checkpatch warning if I don't wrap "mode" in
parenthesis. How about I keep this for now and I will follow up with a
clean up for rest of the macros later ?
