Right, I'm worried that it will be quite hard to maintain this document
once we start adding all the various pmic blocks to it. So if we somehow
can maintain a series of qcom-pm8xxx-<func>.yaml and just ref them into
the main PMIC definition.

@Rob, can you give us some guidance on how to structure this binding,
with the various PMICs described will have some defined subset of a
larger set of hardware blocks that's often shared between versions?

Bjorn
