My statement was intended to be a reduction ad absurdum to the generic naming argument, rather than my public exam on the dt 0.4 spec. I find it useful to have node names that identify the function as clearly as possible, or to see ethernet-phy and usb-phy under /proc/device-tree/soc@0/ and /sys/bus/platform/devices/. That was _my_ goal. Obviously, you and Dmitry disagree with that goal. Alex
