The sub-board contains three MAX96712 connected to the main-board using
I2C and CSI-2, record the connections. Also enable all nodes (VIN, CSI-2
and ISP) that are part of the downstream video capture pipeline.

* Changes since v1
- Rebase on latest renesas-drivers.

Hi Geert,

The bindings and the driver itself are now merged upstream so I think
this is ready to be merged as well. With this final patch capture on V3U
can be demonstrated out-of-the box using the MAX9612 self pattern mode.

A simple test procedure,

        # Configure media graph
        media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':0 [fmt:RGB888_1X24/1920x1080 field:none]"
        media-ctl -d /dev/media0 -V "'rcar_isp fed00000.isp':0 [fmt:RGB888_1X24/1920x1080 field:none]"
        yavta -s 1920x1080 /dev/video0
        v4l2-ctl -v pixelformat=AR24

        # Capture checkerboard pattern
        yavta -c10 --file=frame-#.bin /dev/video0

        # Switch pattern and capture gradients
        yavta --set-control '0x009f0903 1' /dev/v4l-subdev6
        yavta -c10 --file=frame-#.bin /dev/video0

This series is based and tested on the latest available renesas-drivers,
renesas-drivers-2022-01-11-v5.16.
