Subject: [PATCH v3 2/2] ARM: dts: r8a7742-iwg21d-q7-dbcm-ca: Add support for 8-bit ov7725 sensors
The 8-bit ov7725 sensors can also be connected to the camera daughter
board.
This patch creates a separate dtsi file for ov7725 sensors and is included
in r8a7742-iwg21d-q7-dbcm-ca.dts. The user can set VINx_SENSOR depending
on the cameras connected.
