[Ulf Hansson]

Recent updates to the PSCI and the power-domain DT bindings, deserves some
additional improvements on top. This series takes care of this.

[PATCH 1/2] dt-bindings: arm: Add some constraints for PSCI nodes

[Ulf Hansson]

There's no point allowing anything else but "psci" for the corresponding
nodename of the PSCI node, so let's make this an explicit requirement.

Moreover, let's also prevent additional properties, which also allows a
better verification of the "patternProperties" bindings for subnodes.

[PATCH 2/2] dt-bindings: power: Fix example for power-domain

[Ulf Hansson]

The change that converted the domain-idle-states DT bindings to the
json-schema, forgot to update the corresponding example for the
power-domain binding. Let's fix it.
