Subject: [PATCH v2 08/10] v4l: Add signal lock status to source change events
Date: Tue, 19 Jul 2016 17:03:35 -0700 [thread overview]
Message-ID: <1468973017-17647-9-git-send-email-steve_longerbeam@mentor.com> (raw)
In-Reply-To: <1468973017-17647-1-git-send-email-steve_longerbeam@mentor.com>
Add a signal lock status change to the source changes bitmask.
This indicates there was a signal lock or unlock event detected
at the input of a video decoder.
