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.
