-* Bosch BMG160 triaxial rotation sensor (gyroscope)
-
-Required properties:
-
-  - compatible : should be "bosch,bmg160", "bosch,bmi055_gyro" or "bosch,bmi088_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)>;
-};
