I do not think there is any special reason for that, and just might be enabled for the rpi specific config, let's see what our arm* porters say. And if nothing speaks about it we might top-down (in the upper suites first, then maybe down to bookworm) enable it. > CONFIG_KEYBOARD_GPIO is tristate symbol, so if there is space problem, > it can be enabled as loadable module and it would be loaded ondemand > only when needed. In case of yes to above question, it should be enabled as loadable module. Thanks for raising it. Regards, Salvatore
