Thanks, I've added this to my sunxi-wip branch for now.

p.s.
Any progress on getting the "core" H3 kernel support upstream ?
Given Arnd's remarks about how we should not hard-code the
indices in the clk driver + the very KISS nature of the
change to 1 parent-clk per gate setup I still believe
that that one is best.
Maxime ? Chen-Yu ? It would be really good to be able to
move forward with this, how do you want to proceed ?
