I'm actually waiting on the second part of that to land.

The series introducing critical clocks also wanted to provide so called 
hand-off clocks (clocks being critical until a driver takes possession of 
them).

What are currently critical clocks in Rockchip drivers are essentially a mix 
of those two types, and I was somehow hoping that the handoff type also 
lands soonish so that we can limit ourselfs to one conversion step.
