Doing an of_iomap() for every single clock register seems like an
overkill
and might have performance penalties at boot.
the other option might be to use offset and a single allocation - but I
think Tero should comment if this is possible or if registers on some
SoCs are strewn all over the place
Well, currently the basic clock nodes also do their individual
of_iomaps, so doing a tweak only for the OMAP DPLLs is not going to
change the figure much.
A generic solution is needed but I think this was commented elsewhere by
Mike to remain as future optimization (can't find the reference to this
with a quick search though.)
