[PATCH 1/2] dt-bindings: arm: Add some constraints for PSCI nodes
From: Ulf Hansson <hidden>

Subsystem:

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.
