Subject: [PATCH v3 07/13] media: imx: csi: Register a subdev notifier
Date: Tue, 20 Mar 2018 17:37:23 -0700	[thread overview]
Message-ID: <1521592649-7264-8-git-send-email-steve_longerbeam@mentor.com> (raw)
In-Reply-To: <1521592649-7264-1-git-send-email-steve_longerbeam@mentor.com>

Parse neighbor remote devices on the CSI port, add them to a subdev
notifier, and register the subdev notifier for the CSI, by calling
v4l2_async_register_fwnode_subdev().
