Subject: [PATCH v2 3/7] media: rc: per-protocol repeat period and minimum keyup timer
Date: Sun, 8 Apr 2018 22:19:38 +0100 [thread overview]
Message-ID: <e2fd13000586bb0a4e7a2cc07e69ad08319e3519.1523221902.git.sean@mess.org> (raw)
In-Reply-To: <cover.1523221902.git.sean@mess.org>
In-Reply-To: <cover.1523221902.git.sean@mess.org>
Each IR protocol has its own repeat period. We can minimise the keyup
timer to be the protocol period + IR timeout. This makes keys less
"sticky" and makes IR more reactive and nicer to use.
This feature was previously attempted in commit d57ea877af38 ("media: rc:
per-protocol repeat period"), but that did not take the IR timeout into
account, and had to be reverted.
