hi
i have use tc358749 hdmi->mipi csi chip to capture image. i finish the driver on imx8m mini first. and it works well.
and now i want to port the driver on imx8mq . it can not capture the image when the image is up to 1920*1080p@60,
it works well on 1920*1080p@30 and lower resolution. when the image is 1080p@60, the tc358749 mipi lane speed is about 560.25M.
i find the imx8mq use the driver file is mxc-mipi-csi2_yav.c. it is not same with imx8m mini. i don't konw the driver whether or not support 1080P@60, and how to modify it.
Any suggestions are appreciated!
Best regards
