I think the clock and power domain patches need much more review.
They're introducing a couple of new management subsystems which may
be of interest to other SoCs, maybe even different architectures.

Sure the power domain and clock domain code can be worked into
something more generic once we've figured out what can be shared.

I've posted these patches to LKML and linux-pm for other arch people to
look at too.

This is, unfortunately, not so useful to PXA likely. Although there's
power domain and clock domain concepts in PXA silicon, the power
states of those domains are controlled in a integrated way along with
the power state of the whole chip, perhaps to reduce the software
complexity in software domain management, and mimics the ACPI
concepts to some extent.

I don't want to give an early conclusion, but I may look more into the
usage of these power domains and clock domains ( it's not merely
to setup the PRCM registers correctly, no? )

OK, thanks for looking through it.

Well lots of it deals with the omap PRCM registers yeah. But maybe some
of the domain manamgent code could be shared.

Sounds like there's no need to resend these, so please ignore this
email.
