Hello Geert,

This series is the final peace of my video capture enablement of the 
V3U. Unfortunately it depends on dt-bindings not yet available upstream 
and [1] the GPIO expanders patch [2] before it can be integrated.

The good news is that with this series, it dependencies and the related 
driver changes [3] I can operate and capture frames at 1080p @ 30fps 
from all 3 MAX96712 on the falcon-csi-dsi board.

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-2021-04-13-v5.12-rc7.
