Most MFD things are, like I2C chips and stuff but this one sure
match the title "multifunctional device", just that it's very singleton
and very close to the SoC core.

One property of MFD devices is that they register a fixed set of
child devices (cells) that are each providing separate functionality
and have their own drivers. If that's not the case with prcmu,
I think it should not be an MFD driver.

It's both-and. The power domain regulators and cpufreq are
platform devices and will work nicely as MFD cells spawn
off the PRCMU. (Just that nooned did it that way before.)

That looks like a potential candidate for drivers/mfd/. I'd have to look at
the code to take it or not, but it's probably worth trying.

Cheers,
Samuel.
