Subject: [PATCH v8 2/6] dt-bindings: media: sun6i-a31-csi: Add internal output port to the ISP
Date: Thu,  3 Nov 2022 17:37:13 +0100	[thread overview]
Message-ID: <20221103163717.246217-3-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20221103163717.246217-1-paul.kocialkowski@bootlin.com>

Some Allwinner devices come with an Image Signal Processor (ISP) that
allows processing camera data to produce good-looking images,
especially from raw bayer representations.

The ISP does not have a dedicated capture path: it is fed directly by
one of the CSI controllers, which can be selected at run-time.

Represent this possibility as a graph connection between the CSI
controller and the ISP in the device-tree bindings.
