Hi! Cutiepie is a small handheld tablet. It has embedded controller connected via serial to the main system, handling stuff such as power button and battery percentage. Currently they are using userland deamon for communication, but I believe that should eventually go into kernel. For debugging, it would be really nice to be able to attach my module to given serdev. Is such thing possible? I see "[PATCH v2 00/19] Dynamically load/remove serdev devices via sysfs*" series (https://www.spinics.net/lists/linux-serial/msg30732.html) but I'm not sure if equivalent functionality exists in mainline kernel? Is there some kind of similar hardware already supported by mainline? Using driver as a reference might be easier than starting from scratch. Thanks and best regards, Pavel -- People of Russia, stop Putin before his war on Ukraine escalates.
