[PATCH v3 08/13] dt-bindings: arm: cpus: Add a power-domain-name for a performance-domain

From: Ulf Hansson
Date: Fri Aug 25 2023 - 07:28:03 EST


When an CPU's performance domain is managed through the SCMI firmware,
let's enable us describe this as a consumer of a power-domain provider,
which is the de-facto standard to use for performance domains. In this
case, let's specify a corresponding power-domain-name, to point out the
corresponding index for it.
