Subject: [PATCH 5/5] regulator: pca9450: Enable DVS control via PMIC_STBY_REQ
Date: Thu, 28 Apr 2022 16:01:39 +0200 [thread overview]
Message-ID: <20220428140139.7349-5-rickaran@axis.com> (raw)
In-Reply-To: <20220428140139.7349-1-rickaran@axis.com>
From: Rickard x Andersson <rickaran@axis.com>
When DVS is enabled via the devicetree properties
"nxp,dvs-run-voltage" and "nxp,dvs-standby-voltage" then
also the bit that enables DVS control via PMIC_STBY_REQ pin
should be set.
