-Subject: [PATCH] [media] rc: gpio-ir-recv: add timeout on idle
-
-Many decoders require a trailing space (period without IR illumination)
-to be delivered before completing a decode.
-
-Since the gpio-ir-recv driver only delivers events on gpio transitions,
-a single IR symbol (caused by a quick touch on an IR remote) will not
-be properly decoded without the use of a timer to flush the tail end
-state of the IR receiver.
-
-This patch initializes and uses a timer and the timeout field of rcdev
-to complete the stream and allow decode.
-
-The timeout can be overridden through the use of the LIRC_SET_REC_TIMEOUT
-ioctl.
