Dear,
We implement camera on our carried board.
@ our system hw structure
CMSO 12bit → MAX96705(SER) Removes the lower 4 bits of 12 bits = RAW 8bit - MAX9286(DESRI) - MIPI 2 CSI

After saving in RGGB format, when playing back to mplayer Y8 video format, it will scroll up and down.
Is there anything else that needs to be fixed on the kernel side?
