The domain doesn't match the one used to send that patch, is that intentional?

You should be using SUNXI_CCU_GATE_DATA here

Having some consistency here would be great, CLK_R_CPUS would be best I guess.

You're going to need a DT binding here too.

Using the same prefix that we use everywhere else would be nice too.

So we don't really want to expose all the clocks in the binding here, but only
the one that are going to be used by the devices (and not the "internal" ones),
so that will be usually the bus gates and the module gates.

If we need a PLL at some point, we can always export it, but that should be the
exception, not the default.
