[PATCH v2 1/2] ARM: dts: r8a7742-iwg21d-q7-dbcm-ca: Separate out ov5640 nodes

From: Lad Prabhakar
Date: Wed Nov 25 2020 - 08:02:03 EST


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 ov5640 nodes in a dtsi file.
