+* Bosch BMG160 triaxial rotation sensor (gyroscope)
+
+Required properties:
+
+  - compatible : should be "bosch,bmg160" or "bosch,bmi055_gyro"
+  - reg : the I2C address of the sensor (0x69)
+
+Optional properties:
+
+  - interrupts : interrupt mapping for GPIO IRQ, it should by configured with
+               flags IRQ_TYPE_EDGE_RISING
+
+Example:
+
+bmg160@69 {
+       compatible = "bosch,bmg160";
+       reg = <0x69>;
+       interrupt-parent = <&gpio6>;
+       interrupts = <18 (IRQ_TYPE_EDGE_RISING)>;
+};
