dt-bindings:iio:gyro:invensense,mpu3050: txt to yaml format conversion.
Very similar to the mpu6050 binding. Only unusual element is the i2c-gate section. Example tweaked a little to include a real device behind the gate. As Rob Herring suggested, dropped use of explicit i2c-gate yaml binding in favour of just using the i2c-controller.yaml binding directly.

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