Please make sure to address comments that were made against your v2
version, too.

I think you need a "#clock-cells = <1>;" in here. You should also
create a "include/dt-bindings/clock/rockchip,rk808.h" file that lists
numbers for your two clocks.

You should add "clock-output-names" as haoyu,hym8563.txt has.
