Thanks for the patch, overall good stuff there.
Couple of things, though:
- address my comments (consider them against entire series)
- check my patch I sent today to support this from ACPI

I wouldn't like to spread more drivers use specific of_foo_bar stuff where it's
easily to support everything (note: device_property_* calls supports software
fw nodes as well).

Perhaps, you may incorporate my patch into your nice series.
