Yes, I'm well aware of that, but here's the thing...
I'm describing the hardware here.
The real problem is that Dove (etc) went down the path of breaking up
the PMU device into multiple smaller devices each specifying a sub-set
of the register range. By doing that, Dove moved away from describing
the hardware - instead, we've described the Linux _implementation_ with
its separate (sub-)devices - its the implementation's choice that we'd
break up the PMU into these separate devices, almost to the point of
specifying each individual register.
What could be done to work around this oversight is to mvoe these
devices beneath the PMU node, which IMHO makes complete sense as these
are sub-devices of the PMU/PMC rather than separate devices.
