Subject: [PATCH v3 1/3] dt-bindings: mfd: sy7636a: Add missing gpio pins
 and supply

To be able to fully describe how the SY7636A is connected to the system,
add properties for the EN and VCOM_EN pins. To squeeze out every bit
of unused current, in many devices it is possible to power off the
complete chip. Add an input regulator to allow that.
