a central (central as in "one device for SoC") block managing power
which you want to model here?

The pwrstate driver binds to individual power control registers within the syscon node. The parent node is bound by the generic syscon driver, so there is no specific SoC driver for it, but I still want to include SoC-specific compatibles so we can have something to use for quirks if we run into trouble in the future.

There are two PMGRs in the Apple M1, and thus there would be two syscon nodes, each containing one subnode per PM domain. The devicetree in this series currently only instantiates one of those, though.
