Subject: [PATCH 1/2] dt-bindings: arm: Add some constraints for PSCI nodes
Date: Thu, 26 Mar 2020 11:56:25 +0100 [thread overview]
Message-ID: <20200326105626.6369-2-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20200326105626.6369-1-ulf.hansson@linaro.org>
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.
