Compare:

https://github.com/orangepi-xunlong/linux-orangepi/blob/orange-pi-4.9-sun50iw9/drivers/clk/sunxi/clk-sun50iw6.h#L148

https://github.com/orangepi-xunlong/linux-orangepi/blob/orange-pi-4.9-sun50iw9/drivers/clk/sunxi/clk-sun50iw9.h#L158

(This, and experimentation, is also where my "0x20c is the highest
clock-gate-related register" comment on the DTS came from).

Cheers,
Samuel
