Reading what I just wrote makes me think this beast may belong
in drivers/mfd.
Samuel, would you say I can push this driver to MFD?
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.
Yours,
