This series has been tested on a pre-silicon platform, and boots to
prompt (along with DT clocks from Tero).

Silicon & boards are not yet ready. I checked internally about your
request, I had been told that once boards are ready, it can be made
available to the maintainers.

PRCM is derived from AM335x, but modified such that it is more aligned
with OMAP4 (especially w.r.t register offsets)
