I'm going to stick my oar in on this and ask what is a very fundamental
If we're adding the PMU interrupt controller as a separate "device"
aren't we describing our implementation rather than the hardware? It
isn't a separate device as far as the description of it in the reference
Moreover, should the PMU interrupt controller be something which is
handled by a separate chunk of code to a driver for the PMU as a whole,
or are we storing up problems with resource clashes? I can quite see
a PMU driver coming along in the future offering a pair of generic
power domains for the GPU and VPU, and such a driver would need to map
all the PMU registers so it can access the power control, reset and
FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly
improving, and getting towards what was expected from it.
