dba07ad113 dt-bindings: apple,aic: Add affinity description for per-cpu pseudo-interrupts
Some of the FIQ per-cpu pseudo-interrupts are better described with
a specific affinity, the most obvious candidate being the CPU PMUs.

Augment the AIC binding to be able to specify that affinity in the
interrupt controller node.

74703b13f9 dt-bindings: apple,aic: Add CPU PMU per-cpu pseudo-interrupts
Advertise the two pseudo-interrupts that tied to the two PMU
flavours present in the Apple M1 SoC.

We choose the expose two different pseudo-interrupts to the OS
as the e-core PMU is obviously different from the p-core one,
effectively presenting two different devices.

72baffdd26 dt-bindings: interrupt-controller: apple,aic: Add power-domains property
This will bind to the PMGR pwrstate nodes that control power/clock
gating to SoC blocks. The AIC driver doesn't do runtime-pm and likely
never will (since it is system-critical), but it makes sense to describe
the power domain relationship the devicetree properly.
