         * - Name
           - Type
           - Details

         * - ``supply-gpios``
           - ``phandle-array``
           - .. code-block:: none

                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.



         * - ``vin-supply``
           - ``phandle``
           - .. code-block:: none

                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.



         * - ``friendly-name``
           - ``string``
           - .. code-block:: none

                Human readable string describing the sensor. It can be used to
                distinguish multiple instances of the same model (e.g., lid accelerometer
                vs. base accelerometer in a laptop) to a host operating system.

                This property is defined in the Generic Sensor Property Usages of the HID
                Usage Tables specification
                (https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).
