Maybe it should be uint32 with value of 0 and 1? That should be an error because the length is too short so it should go with some default from the code. Looks like there is no user, though no property could mean keep the default/bootloader setting. Can you sort out which type is really desired here and hopefully we can get rid of the other type. It's not the first case of pinctrl properties with multiple types, but we don't really need more. Rob
