On a second thought... I guess you meant something like this?
adc: adc@18101600 {
compatible = "cosmic,10001-adc";
reg = <0x18101600 0x24>;
clocks = <&adc_clk>;
clock-names = "adc";
vref-supply = <®_1v8>;
cosmic,channels {
#address-cells = <1>;
#size-cells = <0>;
channel@0 {
reg = <0>;
};
channel@1 {
reg = <1>;
};
};
};
Might be better, but I don't have a strong opinion on it.
