I agree about /sys/devices -> /sys/devices/platform, that makes more sense The problem with names is that we don't *know* that your devices are at the root and unique. They don't have to be. I have platforms that have several "chips" each containing all the same devices. They need to be de-duped. Maybe the right approach is to build the de-duplication in sysfs itself ?
