想使用vp0--HDMI显示文件系统内容的同时使用vp3--rgb配置bt1120显示摄像头采集图像，目前不能成功。kernel运行起来后一直打印dwhdmi-rockchip fdea0000.hdmi: use tmds mode
log显示出错：
[ 2.702796] [drm:rockchip_rgb_bind] *ERROR7
[ 3.397687] rockchip-drm display-subsystem: bound fd58c000.syscon:rgb (ops 0)
[ 3.398128] rockchip-drm display-subsystem: failed to parse loader memory 大神能不能帮忙看看我是哪里配置有问题，谢啦
