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. > > > H.
