RK3588的DPHY0接lt6911uxe转HDMI抓帧分辨率不对

各位大佬好，我在RK3588开发板的dphy0口接lt6911uxe，然后转接摄像头，目前可以抓帧，但是抓到的只有640x480
抓图命令：
sudo v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=YUYV --stream-mmap=3 --stream-skip=3 --stream-to=./myg2_1920x1080yuyv_$(date +%Y%m%d_%H%M%S).out --stream-count=1 --stream-poll
抓帧日志：

经查看，抓出来的图片分辨率只有640x480。
期间，我修改过lt6911uxe的supported_modes_dphy[]数组，只留下大于1080p的分辨率，重新编译后抓帧仍是640x480。
有哪位大佬解决过类似问题？不吝指导，多谢
