Subject: [PATCH v4 1/2] ARM: dts: r8a7742-iwg21d-q7-dbcm-ca: Separate out ov5640 nodes
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
The camera daughter board can also be connected to 8-bit ov7725 sensors,
so in preparation for configurable option to choose depending on the
camera's connected separate out the ov5640 nodes in a dtsi file.
