Subject: [PATCH] arm64: dts: fsl: imx8mq-evk: link regulator to VPU domain
Date: Sun, 5 Dec 2021 15:01:43 -0600 [thread overview]
Message-ID: <20211205210144.1072721-1-aford173@gmail.com> (raw)
The SW1C regulator powers the VPU and the state isn't guaranteed
to always be on. Link the VPU power-domain to the regulator to
ensure it is turned on before using the power domain.
