+Invensense MPU-3050 Gyroscope device tree bindings
+
+Required properties:
+  - compatible : should be "invensense,mpu3050"
+  - reg : the I2C address of the sensor
+
+Optional properties:
+  - interrupt-parent : should be the phandle for the interrupt controller
+  - 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>;
+		};
+	};
+};
