dt-bindings:iio:imu:invensense,mpu6050: txt to yaml conversion
As Rob Herring suggested, this no long requires the explicit i2c-gate binding, but instead just used i2c-controller.yaml directly. 2 prior examples combinded into one as a single example can show all of the binding elements as long as the right part is selected.

InvenSense MPU-6050 Six-Axis (Gyro + Accelerometer) MEMS MotionTracking Device
|
||||
|
||||
http://www.invensense.com/mems/gyro/mpu6050.html
|
||||
|
||||
Required properties:
|
||||
- compatible : should be one of
|
||||
"invensense,mpu6000"
|
||||
"invensense,mpu6050"
|
||||
"invensense,mpu6500"
|
||||
"invensense,mpu6515"
|
||||
"invensense,mpu9150"
|
||||
"invensense,mpu9250"
|
||||
"invensense,mpu9255"
|
||||
"invensense,icm20608"
|
||||
"invensense,icm20609"
|
||||
"invensense,icm20689"
|
||||
"invensense,icm20602"
|
||||
"invensense,icm20690"
|
||||
"invensense,iam20680"
|
||||
- reg : the I2C address of the sensor
|
||||
- interrupts: interrupt mapping for IRQ. It should be configured with flags
|
||||
IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
|
||||
IRQ_TYPE_EDGE_FALLING.
|
||||
|
||||
Refer to interrupt-controller/interrupts.txt for generic interrupt client node
|
||||
bindings.
|
||||
|
||||
Optional properties:
|
||||
- vdd-supply: regulator phandle for VDD supply
|
||||
- vddio-supply: regulator phandle for VDDIO supply
|
||||
- mount-matrix: an optional 3x3 mounting rotation matrix
|
||||
- i2c-gate node. These devices also support an auxiliary i2c bus. This is
|
||||
simple enough to be described using the i2c-gate binding. See
|
||||
i2c/i2c-gate.txt for more details.
|
||||
|
||||
Example:
|
||||
mpu6050@68 {
|
||||
compatible = "invensense,mpu6050";
|
||||
reg = <0x68>;
|
||||
interrupt-parent = <&gpio1>;
|
||||
interrupts = <18 IRQ_TYPE_EDGE_RISING>;
|
||||
mount-matrix = "-0.984807753012208", /* x0 */
|
||||
"0", /* y0 */
|
||||
"-0.173648177666930", /* z0 */
|
||||
"0", /* x1 */
|

"-1", /* y1 */

|

"0", /* y2 */
|

"0.984807753012208"; /* z2 */
|
||||
};

|

|
||||
mpu9250@68 {
|
||||
compatible = "invensense,mpu9250";
|
||||
reg = <0x68>;
|
||||
interrupt-parent = <&gpio3>;
|
||||
interrupts = <21 IRQ_TYPE_LEVEL_HIGH>;
|
||||
i2c-gate {
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
ax8975@c {
|
||||
compatible = "ak,ak8975";
|
||||
reg = <0x0c>;
|

};
