This was implemented as a fallback in of_parse_own_gpio(). Commit d1d564ec4992 ("gpio: move hogs into GPIO core") moved hog parsing into the GPIO core and removed this fallback. Consequently, GPIO hogs without a line-name property are now displayed with a ? in /sys/kernel/debug/gpio. Is this an intentional change, or should the fallback to the DT node name be retained? regards Frank
