    +AK5558 8 channel differential 32-bit delta-sigma ADC
    +
    +This device supports I2C mode only.
    +
    +Required properties:
    +
    +- compatible : "asahi-kasei,ak5558"
    +- reg : The I2C address of the device.
    +
    +Optional properties:
    +
    +- reset-gpios: A GPIO specifier for the power down & reset pin.
    +
    +Example:
    +
    +&i2c {
    + ak5558: adc@10 {
    + compatible = "asahi-kasei,ak5558";
    + reg = <0x10>;
    + reset-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>;
    + };
    +};
