+* Freescale FXAS21002C Digital Angular Rate Gyroscope
+
+Required properties:
+
+  - compatible: must be "fsl,fxas21002c"
+  - reg : the I2C address of the sensor
+
+Optional properties:
+
+  - interrupts		: The first interrupt listed must be the one
+			  connected to the INT1 pin, the second interrupt
+			  listed must be the one connected to the INT2 pin.
+			  The interrupts can be triggered on rising or falling
+			  edges alike.
+			  see interrupt-controller/interrupts.txt
+  - vdd-supply		: The main voltage regulator
+  - iovdd-supply	: The IO voltage regulator
+			  see regulator/regulator.txt
+  - reset-gpios		: GPIO used to reset the device.
+			  see gpio/gpio.txt.
+  - mount-matrix	: see iio/mount-matrix.txt

+Example:

+	compatible = "fsl,fxas21002c";
+	reg = <0x20>;
+	reset-gpios = <&gpio0 2 0>;
+	vdd-supply = <&vref>;
