Whether camera is or is not supported, is defined by presence of camera node or by its status field. Existing firmware (e.g. U-Boot) is also doing this - patching DTS when needed. I do not think introducing some parallel way makes any sense, so no, that's not the way to do it. Best regards, Krzysztof
