      GPIO specifier that controls power to the device.

      This property should be provided when the device has a dedicated
      switch that controls power to the device.  The supply state is
      entirely the responsibility of the device driver.

      Contrast with vin-supply.

    description: |
      Reference to the regulator that controls power to the device.
      The referenced devicetree node must have a regulator compatible.

      This property should be provided when device power is supplied
      by a shared regulator.  The supply state is dependent on the
      request status of all devices fed by the regulator.

      Contrast with supply-gpios.  If both properties are provided
      then the regulator must be requested before the supply GPIOS is
      set to an active state, and the supply GPIOS must be set to an
      inactive state before releasing the regulator.
