You just removed the other file, no folding happened here. Drop the
accdet node and fold this into parent.

Best regards,

Sorry, I'm still not sure what you mean by folding here then. Right now the
accdet is a subnode of the PMIC. If you want me to remove the accdet node, where
would its compatible and property go?

    pmic {
        compatible = "mediatek,mt6359";
        interrupt-controller;
        #interrupt-cells = <2>;

        accdet {
            compatible = "mediatek,mt6359-accdet";
            mediatek,hp-eint-high;
        };
    };

Thanks,
Nícolas
