Subject: [PATCH] ARM: dts: r8a7742-iwg21d-q7-dbcm-ca: Add OV7725 nodes
Date:   Fri, 20 Nov 2020 15:13:43 +0000
Message-Id: <20201120151343.24175-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
Precedence: bulk

Add the ov7725 endpoint nodes to the camera daughter board. The ov7725
sensors can be populated on I2C{0,1,2,3} buses.

By default the VIN{0,1,2,3} are tied to OV5640{0,1,2,3} endpoints
respectively in the camera DB dts hence the remote-endpoint property in
OV7725{0,1,2,3} endpoints is commented out.
