Again I see a lot of holes in there. Please make sure there is only
clocks in the whole region you are claiming for the device.

Otherwise it is fine to register as many controller as necessary

Looks like a copy/paste of the C3. If this pattern keeps on repeating,
it would be nice to make a common definition

The GIC has a driver. If it needs clock, maybe it should request it and
enable it, maybe as optional.

This comment looks like a clock that should be passed as ressource to a
bus or power-domain to be properly manage. This is a pattern that keeps
on repeating. I will not block you on it this time around but I strong
suggest you fix up the situation on the related platform. Next time
around, the reason won't be a valid one.

Again, it is fine when it happens once, like the c3.
When the pattern starts repeating, it is time to do something about it.
