From 0b186c0825f710a937578dc7d2ffbe125ddee7a3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 18 Oct 2015 21:17:25 -0600 Subject: input: Allow repeat filtering to be disabled Generally the input library handles processing of a list of scanned keys. Repeated keys need to be generated based on a timer in this case, since all that is provided is a list of keys current depressed. Keyboards which do their own scanning will resend codes when they want to inject a repeating key. Provide a function which tells the input library to accept repeating keys and not to try to second-guess the caller.
