Kernel-4.18.0-80.el8_invensense,mpu3050

Invensense MPU-3050 Gyroscope device tree bindings

Required properties:

  • compatible : should be “invensense,mpu3050”
  • reg : the I2C address of the sensor

Optional properties:

  • interrupt-parent : should be the phandle for the interrupt controller
  • 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>;
    };
};

};
