Subject: [PATCH v2 03/11] dt-bindings: regulator: pca9450: Document nxp,sd-vsel-fixed-low property for LDO5
Date: Wed, 27 Nov 2024 17:42:19 +0100	[thread overview]
Message-ID: <20241127164337.613915-4-frieder@fris.de> (raw)
In-Reply-To: <20241127164337.613915-1-frieder@fris.de>

From: Frieder Schrempf <frieder.schrempf@kontron.de>

This new property can be used for boards which have the SD_VSEL tied
to a fixed low level. The voltage of LDO5 is therefore only controlled
by writing to the LDO5CTRL_L register.
