I wonder if you could move out the fixed rate clocks into their own
nodes. Are they actually controlled by the same block? If they are
just fixed, you can use the normal binding for fixed rate clocks
and only describe the clocks that are related to the driver.

In my view having these clocks grouped together looks more convincing. After
all, they all share the same I/O regs in order to read configuration.

The fact that they share a register is not making them a group. That's
just a HW design decision and you need to deal with that by protecting
the register access, but not by trying to group them artificially at
the functional level.

I'd disagree with that: The clock controller is the device that owns the
registers and that should be one node in DT, as Paul's first version does.

The part I'm still struggling with is understanding how the fixed-rate
clocks are controlled through those registers. If they are indeed configured
through the registers, the name is probably wrong and should be changed
to whatever kind of non-fixed clock this is.
