I think you may be able to leave out this driver like code
from arch/arm/mach-omap2 by using the existing syscon mapping
we have in the .dtsi files? See for example how the PBIAS
is using the syscon in drivers/regulator/pbias-regulator.c.
If the clock registers don't fall into the existing SCM syscon
area, we can also set up more syscon areas.

Tony
