Subject: [PATCH 1/8] dt-bindings: soc: qcom,rpmh-rsc: Require power-domains
Date: Wed, 31 May 2023 15:22:35 +0200 [thread overview]
Message-ID: <20230531-topic-rsc-v1-1-b4a985f57b8b@linaro.org> (raw)
In-Reply-To: <20230531-topic-rsc-v1-0-b4a985f57b8b@linaro.org>
The Linux RPMh implementation refrains from sending some RPMh votes until
the system is about to enter suspend (which is indicated by all CPU cores
entering a low-power state). Lack of the power-domains property will make
it such that these votes are never sent.
Require the power-domains property as discussed in [1].
