35.4.1 GMSL AR0233 YUV422 camera, 8 channels (MIPI0 4 channels, MIPI1 4 channels) acquisition is normal,
After the upgrade to 35.5.0, four channels of MIPI0 are normal for the first time, but frame loss occurs after four channels of MIPI1 are run.
Go back to run MIPI0 4 all lost frames, has been unable to recover, unless brush machine

v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1200,pixelformat=UYVY --stream-mmap --stream-count=1000 --stream-to=/tmp/stream.yuv
This command is normal to capture frame rates
