Honestly, I am not sure about what the regulator-fixed-domain intends

Perhaps Mark can chime in and spread some light over this?
IIRC it's for situations where there's a device that's normally built as
a separate chip that got built into a bigger SoC and wants to rear end
something onto a power domain, I guess especially if the power domain
doesn't cover the whole of a Linux device.
