Subject: [PATCH v2 03/11] dt-bindings: regulator: pca9450: Document nxp,sd-vsel-fixed-low property for LDO5

From: Frieder Schrempf <frieder.schrempf@...tron.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.
