Why is this needed?
These are needed for the drivers which have still the mxs-mmc.* names
to find their clocks. Alternatively we could also add the appropriate
clocks to the clock file. Don't know if that's better though.
Ah, yes I should have known that... If clk lookup is all that's needed,
I'd suggest adding the necessary clk lookups either here or in the clock
code. Not much difference, but at least it removes the use of
*_BASE_ADDR defines.
Agreed we do this on AT91
I'm willing to do like that.
But i'm new to this, can you help point our where the code i can reference
in Rob suggested way?
