Subject: [PATCH 06/14] media: sun6i-csi: Support feeding from the MIPI CSI-2 controller
Date: Fri, 23 Oct 2020 19:45:38 +0200 [thread overview]
Message-ID: <20201023174546.504028-7-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20201023174546.504028-1-paul.kocialkowski@bootlin.com>
The A31 CSI controller supports MIPI CSI-2, through a dedicated controller.
The MIPI CSI-2 controller (which differs between A31 and A83T) is supported
as a separate driver and connected through the fwnode graph.
The two controllers are likely connected through some kind of FIFO,
so the CSI controller doesn't have much to do itself except for selecting
the MIPI CSI-2 input.
