Usually the original author is a good choice, which I think happens to be the subsystem maintainer...

The compatible itself does not provide auto-detection, it's the opposite - the driver must perform auto detection if this compatible is used. > + enum: > + - abracon,abx80x > + - abracon,ab0801 > + - abracon,ab0803 > + - abracon,ab0804 > + - abracon,ab0805 > + - abracon,ab1801 > + - abracon,ab1803 > + - abracon,ab1804 > + - abracon,ab1805 > + - microcrystal,rv1805 > + > + reg: > + maxItems: 1 > + > + abracon,tc-diode: > + description: > + Trickle-charge diode type. > + Required to enable charging backup battery. > + > + Supported are 'standard' diodes with a 0.6V drop > + and 'schottky' diodes with a 0.3V drop. > + $ref: /schemas/types.yaml#/definitions/string > + enum: > + - standard > + - schottky > + > + abracon,tc-resistor: > + description: > + Trickle-charge resistor value in kOhm. > + Required to enable charging backup battery. > + $ref: /schemas/types.yaml#/definitions/uint32 > + enum: [0, 3, 6, 11] > + > +required: > + - compatible > + - reg > + > +unevaluatedProperties: false > + > +examples: > + - | > + #include <dt-bindings/interrupt-controller/irq.h> > + > + rtc@69 { > + compatible = "abracon,abx80x"; > + reg = <0x69>; You'll have to make a "fake" i2c bus here to satisfy the tooling. There should be lots of examples for how to do this in other rtc bindings.
