Subject: [PATCH v8 7/9] ARM: dts: sun8i: a83t: Add MIPI CSI-2 controller node
Date: Fri,  4 Jul 2025 17:46:24 +0200	[thread overview]
Message-ID: <20250704154628.3468793-8-paulk@sys-base.io> (raw)
In-Reply-To: <20250704154628.3468793-1-paulk@sys-base.io>

From: Paul Kocialkowski <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 is connected to the only CSI
receiver with a fwnode graph link. Note that the CSI receiver supports
both this MIPI CSI-2 source and a parallel source.

An empty port with a label for the MIPI CSI-2 sensor input is also
defined for convenience.
