Subject: [PATCH v3 08/17] media: imx: mipi csi-2: Create media links in bound notifier
Date: Tue, 4 Feb 2020 15:49:09 -0800 [thread overview]
Message-ID: <20200204234918.20425-9-slongerbeam@gmail.com> (raw)
In-Reply-To: <20200204234918.20425-1-slongerbeam@gmail.com>
Implement a notifier bound op to register media links from the remote
sub-device's source pad(s) to the mipi csi-2 receiver sink pad.
Signed-off-by: Steve Longerbeam <slongerbeam@gmail.com>
---
Changes in v3:
- call a local imx-media utility imx_media_create_fwnode_pad_link()
that creates a single link.
