Subject: [PATCH v3 08/13] dt-bindings: arm: cpus: Add a power-domain-name for a performance-domain
Date: Fri, 25 Aug 2023 13:26:28 +0200	[thread overview]
Message-ID: <20230825112633.236607-9-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20230825112633.236607-1-ulf.hansson@linaro.org>

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.
