Subject: [PATCH 10/14] ARM: dts: sun8i: v3s: Add MIPI D-PHY and MIPI CSI-2 interface nodes
Date: Fri, 23 Oct 2020 19:45:42 +0200
Message-ID: <20201023174546.504028-11-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20201023174546.504028-1-paul.kocialkowski@bootlin.com>

MIPI CSI-2 is supported on the V3s with an A31 controller, which seems
to be used on all Allwinner chips supporting it, except for the A83T.
The controller is connected to CSI0 through fwnode endpoints.
The mipi_csi2_in port node is provided to connect MIPI CSI-2 sensors.

The D-PHY part is the same that already drives DSI, but used in Rx mode.
