+Invensense MPU-3050 Gyroscope device tree bindings
+
+Required properties:
+ - compatible : should be "invensense,mpu3050"
+ - reg : the I2C address of the sensor
+
+Optional properties:
+ - interrupts : interrupt mapping for the trigger interrupt from the
+ internal oscillator. The following IRQ modes are supported:
+ IRQ_TYPE_EDGE_RISING, IRQ_TYPE_EDGE_FALLING, IRQ_TYPE_LEVEL_HIGH and
+ IRQ_TYPE_LEVEL_LOW. The driver should detect and configure the hardware
+ for the desired interrupt type.
+ - vdd-supply : supply regulator for the main power voltage.
+ - vlogic-supply : supply regulator for the signal voltage.
+ - mount-matrix : see iio/mount-matrix.txt
+
+Optional subnodes:
+ - The MPU-3050 will pass through and forward the I2C signals from the
+ incoming I2C bus, alternatively drive traffic to a slave device (usually
+ an accelerometer) on its own initiative. Therefore is supports a subnode
+ i2c gate node. For details see: i2c/i2c-gate.txt
+
+Example:
+
+mpu3050@68 {
+ compatible = "invensense,mpu3050";
+ reg = <0x68>;
+ interrupt-parent = <&foo>;
+ interrupts = <12 IRQ_TYPE_EDGE_FALLING>;
+ vdd-supply = <&bar>;
+ vlogic-supply = <&baz>;
+
+ /* External I2C interface */
+ i2c-gate {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ fnord@18 {
+ compatible = "fnord";
+ reg = <0x18>;
+ interrupt-parent = <&foo>;
+ interrupts = <13 IRQ_TYPE_EDGE_FALLING>;
+ };
+ };
+};

+* 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>;
+};
