So that is this: > + if (type == PIN_MAP_TYPE_INVALID) > + type = PIN_MAP_TYPE_CONFIGS_GROUP; > + dt_pin_specifier = "groups"; This is just kludgy. There are only two kernel-internal users of this function, refactor the function signature and change the other callers over instead, patch the drivers. Take this opportunity to add some kerneldoc above the pinconf_generic_dt_subnode_to_map() and give the function a reasonable signature. BTW: this is just for config settings for groups right? Not for muxing I hope? Yours, Linus Walleij
