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>;
};
};
