你试一试改过 sun8i-v3s.dtsi 文件 里面的:

builtin_platform_driver(sun8i_v3s_pinctrl_driver);就可以了,
估计是这个:
&panel {
compatible = "urt,umsh-8596md-t", "simple-panel";
};会去初始化panel那组引脚,而没有找到定义.

我用的480*272的屏幕，应该理论上uboot更换一下，设备树更换一下就可以了吧？

@john78
原因是pinctrl驱动中对pe引脚定义的lcd功能名称和设备树中的不一致导致的，只需要将设备树做如下修改就好了
lcd_rgb666_pins_a: lcd-rgb666-pe {
pins = "PE0", "PE1", "PE2", "PE3", "PE4", "PE5",
"PE6", "PE7", "PE8", "PE9", "PE10", "PE11",
"PE12", "PE13", "PE14", "PE15", "PE16", "PE17",
"PE18", "PE19", "PE23", "PE24";
function = "lcd"; /*licheepi 4.13y版本的设备树此处为function = "lcd0"， 但是驱动中是 "lcd"*/
};
即：function = "lcd0"; -> function = "lcd";

按这个方法还是没有解决

如果使用sun8i-v3s-licheepi-zero-dock.dts，就完全不能驱动屏幕
