What's wrong with using 0xff? Ie. something like this: bus=ahb,qmi-chip-id=0,qmi-board-id=255,variant=foo Or maybe even just skip qmi-board-id entirely if it's not supported? So that the board file string would be something like: bus=ahb,qmi-chip-id=0,variant=foo I really would like to avoid adding more DT properties unless it's absolutely critical. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
