Shouldn't this be implemented at a lower-level layer like the input > subsystem? No, this patch is implementing what the microcontroller does, i.e. 10 presses + 1 release. I'm not sure it is the right level to do it (the rate/delay should be at least customizable from the board), but the logic is right and if someone else needs more configurability we can add it later.
