The response was effectively "use udev": https://lore.kernel.org/all/20240519144920.14804-1-egyszeregy@xxxxxxxxxxx/ https://lore.kernel.org/all/20240519211346.30323-1-egyszeregy@xxxxxxxxxxx/ This definitely is in "devicetree properties are not for software-policy" territory to me, maybe Rob's changed his mind since 2021.
