InvenSense MPU-6050 Six-Axis (Gyro + Accelerometer) MEMS MotionTracking Device
http://www.invensense.com/mems/gyro/mpu6050.html
Required properties:
- compatible : should be "invensense,mpu6050"
- reg : the I2C address of the sensor
- interrupt-parent : should be the phandle for the interrupt controller
- interrupts : interrupt mapping for GPIO IRQ
Optional properties:
- mount-matrix: an optional 3x3 mounting rotation matrix
Example:
mpu6050@68 {
compatible = "invensense,mpu6050";
reg = <0x68>;
interrupt-parent = <&gpio1>;
interrupts = <18 1>;
mount-matrix = "-0.984807753012208", /* x0 */
"0", /* y0 */
"-0.173648177666930", /* z0 */
"0", /* x1 */
"-1", /* y1 */
"0", /* z1 */
"-0.173648177666930", /* x2 */
"0", /* y2 */
"0.984807753012208"; /* z2 */
};
