As rk3368 contained two separated iodomain areas, this was
determined to use which regmap base address.

I don't think we need to specify this on a driver level. Both GRF areas
are
"General register files" only located in two separate power-domains.
So the rockchip,grf property should work for both. Especially as nothing
keeps designers from introducing yet another GRF-area somewhere else ;-)

From when I started working on the rk3368, I still have a preliminary
patches for that sitting here, so I've attached on how I envisoned that to
work.
Okay, i agree to you, but it make someone a little confused just from
the drive code,
not DT file,  about  pmugrf regmap base address.:-)

How do you feel about intergating GRF and PMU drivers in one driver?
Thanks!
I will very strongly disagree here ;-) .
Similar to the power-domains being part of the pmu, the io-domains are
part of their individual GRFs. So if you want it really clean and tidy the way 
to go foward will be the attached patches. Compile-tested only.

Other things like the usbphy control should move there as well in the long 
run. But that's not immediate necessary.
