Subject: [PATCH v3 7/8] ARM: dts: sun8i: a83t: Add MIPI CSI-2 controller node
Date: Wed,  2 Mar 2022 22:10:59 +0100	[thread overview]
Message-ID: <20220302211100.65264-8-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20220302211100.65264-1-paul.kocialkowski@bootlin.com>

MIPI CSI-2 is supported on the A83T with a dedicated controller that
covers both the protocol and D-PHY. It can be connected to the CSI
interface as a V4L2 subdev through the fwnode graph.

This is not done by default since connecting the bridge without a
subdev attached to it will cause a failure on the CSI driver.
