Subject: [PATCH v3 04/17] media: imx: mipi csi-2: Implement get_fwnode_pad op
Date: Tue,  4 Feb 2020 15:49:05 -0800	[thread overview]
Message-ID: <20200204234918.20425-5-slongerbeam@gmail.com> (raw)
In-Reply-To: <20200204234918.20425-1-slongerbeam@gmail.com>

Implement get_fwnode_pad operation. If the endpoint is owned by the MIPI
CSI-2 receiver, return the endpoint's port number. The MIPI CSI-2 receiver
maps port numbers and pad indexes 1:1.
