Sure! Will do in v4.

Sure! Don't know why I didn't notice that.

doesn't hurt to use the facilities available.

Thanks for the reviews! I'll roll them all into v4 shortly.

While I'm at it: I think I have Reviewed-by's for all the DT patches
(except this one). Given it also touches Rockchip device trees, maybe
this all needs to go through Heiko / linux-rockchip? Or if not, it'd be
nice if Heiko spoke up to tell the devfreq maintainers instead.
