20f47443db dt-bindings: arm: apple: apple,pmgr-pwrstate: Add A7-A11, T2 compatibles
The blocks found on Apple A7-A11 SoCs are compatible with the existing
driver so add their per-SoC compatible.

4d93b3a974 dt-bindings: power: apple,pmgr-pwrstate: Add t8112 compatible
Add the apple,t8112-pmgr-pwrstate compatible for the Apple M2 SoC.

This goes after t8103. The sort order logic here is having SoC numeric
code families in release order, and SoCs within each family in release
order:

- t8xxx (Apple HxxP/G series, "phone"/"tablet" chips)
  - t8103 (Apple H13G/M1)
  - t8112 (Apple H14G/M2)
- t6xxx (Apple HxxJ series, "desktop" chips)
  - t6000 (Apple H13J(S)/M1 Pro)
  - t6001 (Apple H13J(C)/M1 Max)
  - t6002 (Apple H13J(D)/M1 Ultra)

Note that t600[0-2] share the t6000 compatible where the hardware is
100% compatible, which is usually the case in this highly related set
of SoCs.

d824dade33 dt-bindings: power: apple,pmgr-pwrstate: Add apple,min-state prop
A few devices (DCP/DCPEXT) need to have the minimum power state for
auto-PM configured. Add a property that allows the DT to specify this
value.

e8117f85b9 dt-bindings: power: Add apple,pmgr-pwrstate binding
This syscon child node represents a single SoC device controlled by the
PMGR block. This layout allows us to declare all device power state
controls (power/clock gating and reset) in the device tree, including
dependencies, instead of hardcoding it into the driver. The register
layout is uniform.

Each pmgr-pwrstate node provides genpd and reset features, to be
consumed by downstream device nodes.

Future SoCs are expected to use backwards compatible registers, and the
"apple,pmgr-pwrstate" represents any such interfaces (possibly with
additional features gated by the more specific compatible), allowing
them to be bound without driver updates. If a backwards incompatible
change is introduced in future SoCs, it will require a new compatible,
such as "apple,pmgr-pwrstate-v2".
