---dts 配置如下：
{
disp_timings: display-timings {
native-mode = <&timing0>;
timing0: timing0 {
screen-type = <SCREEN_LVDS>;
lvds-format = <LVDS_6BIT>;
out-face = <OUT_P666>;
color-mode = <COLOR_RGB>;
clock-frequency = <40000000>; /* ? */
hactive = <800>;
vactive = <600>;
hback-porch = <110>;
hfront-porch = <126>;
hsync-len = <20>;
vback-porch = <10>;
vfront-porch = <12>;
vsync-len = <6>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <1>;
swap-rb = <0>;
swap-rg = <0>;
swap-gb = <0>;
};
};
};
液晶屏是 lvds 单6。 如上设置后，背光正常， 液晶屏完全不亮。
