* NXP FXAS21002C Gyroscope device tree bindings

http://www.nxp.com/products/sensors/gyroscopes/3-axis-digital-gyroscope:FXAS21002C

Required properties:

  - compatible : should be "nxp,fxas21002c"

  - reg : the I2C address of the sensor or SPI chip select number for the

          device.

  - vdd-supply: phandle to the regulator that provides power to the sensor.

  - vddio-supply: phandle to the regulator that provides power to the bus.

Optional properties:

  - reset-gpios : gpio used to reset the device, see gpio/gpio.txt

  - interrupts : device support 2 interrupts, INT1 and INT2,

                 the interrupts can be triggered on rising or falling edges.

                 See interrupt-controller/interrupts.txt

  - interrupt-names: should contain "INT1" or "INT2", the gyroscope interrupt

                     line in use.

  - drive-open-drain: the interrupt/data ready line will be configured

                      as open drain, which is useful if several sensors share

                      the same interrupt line. This is a boolean property.

                      (This binding is taken from pinctrl/pinctrl-bindings.txt)

Example:

gyroscope@20 {

	compatible = "nxp,fxas21002c";

	reg = <0x20>;

	vdd-supply = <&reg_peri_3p15v>;

	vddio-supply = <&reg_peri_3p15v>;
