Please don't store all Apple-related bindings in bindings/arm/apple, but
instead group per device type like in most of other bindings. In this
case - this looks like something close to power domain controller, so it
should be in bindings/power/
This is a controller that, right now, is only used to instantiate device
power management controls, but the controller itself is just a generic
syscon device. Depending on the register range, it could conceivably
encompass other register types (e.g. clock selects) within it, though
I'm not sure I want to do that right now. Apple calls several of these
different register sets as a whole a "PMGR". So I'm not sure if it
really qualifies as "just" a power domain controller. If we want to
restrict this to the power state portion of PMGR, then it might make
sense to call it something more specific...
See arm/rockchip/pmu.yaml for the setup this is modeled after.
No power-domain-cells? Why? What exactly this device is going to do?
Maybe I'll check the driver first.... :)
It's a syscon, it does nothing on its own. All the work is done by the
child nodes and the driver that binds to those.

Fixed for v2.
