This is a problem other IR drivers suffer from too. It might be better to send a IR timeout event like st_rc_send_lirc_timeout() in st_rc.c, with the duration set to what the timeout was. That is what irraw timeouts are for; much better than fake transitions. > This patch adds an optional device tree node "flush-ms" which, if > present, will use a jiffie-based timer to complete the last pulse > stream and allow decode. A common value for this is 100ms, I'm not sure what use it has to have it configurable. It's nice to have it exposed in rc_dev->timeout.
