see notes on mrvl, and the usage of very generic names. Maybe find a
better name than the generic 'mpic'?

you mis-spelled MPIC as PMIC.

I'd say that given you already have a clock-frequency field, just use
that and detect == 25MHz.
Personally, I would have added a static clock to give to the timer
something to reference.

See above comment.
