please sort nodes by address. ffa30000 should be placed below hdmi at ff980000
and above qos at ffaa0000 .

Sure, will fix that in v4.

As indicated before I don't trust that a generic binding will work for
everything, so I would feel safer if we had a "rockchip,rk3288-mali" in
front for future purposes, making it a

		compatible = "rockchip,rk3288-mali", "arm,mali-t760", "arm,mali-midgard";

OK, sorry I overlooked this part.  I'll add it in v4 with a
vendor compatible string in the binding documentation.

great, thanks :-)

Wasn't there a wish for opp-v2 in a previous version?

Well it wasn't entirely clear to me in Rob's email whether it was
necessary to use opp-v2 now or rather if it would be a potential
option whenever opp-v2 was needed.  If operating-points (v1) are
being deprecated then I can change that in my next patch v4.
Using operating-points-v2 with the Mali driver works as far as I
can tell on rk3288 so that's not an issue.

I don't care to much either way, just remembered it being mentioned
in the previous version. So lets see what Rob says.
