Subject: [PATCH 1/6] dt-bindings: regulator: pca9450: Document new usage of sd-vsel-gpios

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

The sd-vsel-gpios property is abandoned in its current meaning as an
output. We now use it to specify an optional signal that can be
evaluated by the driver in order to retrieve the current status
of the SD_VSEL signal that is used to select the control register
of LDO5.
