From b203bb5f6219e84966889497e63f8a2cf8db7f0c Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 26 Mar 2020 11:56:25 +0100 Subject: [PATCH] dt-bindings: arm: Add some constraints for PSCI nodes 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.
