See also an explanation and list of examples (not exhaustive) in DT specification: https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation > + compatible = "touchnetix,axiom-ax54a"; > + reg = <0x66>; > + interrupt-parent = <&gpio2>; > + interrupts = <2 IRQ_TYPE_EDGE_FALLING>; > + irq-gpios = <&gpio2 0 GPIO_ACTIVE_LOW>; Eh? This looks really wrong. Best regards, Krzysztof
