I think Steffen had a similar approach and we turned it down:
Your proposal lets the clkc map the SLCR's registers. I think
that approach is not right. It might be okay now, since the
SLCR driver is pretty much a useless skeleton. But in general,
there is a driver for the SLCR which maps that register
region. No other driver should mess with it.
Actually, one early version of my clkc looked pretty much like what you
propose now and we changed it because of above reason.
