                          I have set up an i2c protocol which detects the mpu9250 at address 0x68. Now I want to configure the mpu and I have updated my dts file with the following lines of code:

    mpu9250@68 {
        compatible = "invensense,mpu9250";
        reg = ;
        i2c-gate {
            #address-cells = ;
            #size-cells = ;
            ax8975@c {
                compatible = "ak,ak8975";
                reg = ;
            };
        };
    };

However, I get the following error on running >> dmesg | grep mpu

>> inv-mpu6050-i2c 1-0068: invalid whoami 0x40 expected 0x71 (MPU9250)

For this I have also configured the i2cmux and Industrial I/O (IIO) through the developer shell with the "make menuconfig" command. But I see no expected results. Where could I have possibly gone wrong?
