On second though, I guess you can turn these into a single
property named "mpmc-timings" or such and then just copy
them to the registers.
I also wonder whether the timings are actually correct for your
dm9000 device. Maybe the additional gpio read in there was
just an indication that someone worked around incorrect timings?
