+* 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:
+gyroscope@20 {
+ compatible = "fsl,fxas21002c";
+ reg = <0x20>;
+ reset-gpios = <&gpio0 2 0>;
+ vdd-supply = <&vref>;
+ iovdd-supply = <&vref2>;
+ interrupt-parent = <&foo>;
+ interrupts = <0 IRQ_TYPE_EDGE_RISING>,
+ <1 (IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING)>;
