invensense mpu9250 ak8963 and devicetree

[Philippe De Muyter <phdm@macq.eu>]

Hello,

I am trying to use a mpu9250 imu, but I have trouble with the ak8963 part.

Currently, ak8975_probe fails in this code :

        /* Fetch the regulators */
        data->vdd = devm_regulator_get(&client->dev, "vdd");
        if (IS_ERR(data->vdd))
                return PTR_ERR(data->vdd);
        data->vid = devm_regulator_get(&client->dev, "vid");
        if (IS_ERR(data->vid))
                return PTR_ERR(data->vid);

but Documentation/devicetree/bindings/iio/magnetometer/asahi-kasei,ak8975.yaml
says :

  vdd-supply:
    description: |
      an optional regulator that needs to be on to provide VDD power to
      the sensor.

I have no vdd or vdd-supply property in my ak8963 description.

Is that unrelated ?

What should I write in my dts file for this ak8963 embedded in a mpu9250 ?

Thanks in advance

Philippe
