使用京东方15吋 NT156FHM无法点亮，之前已成功点亮群创edp屏，
但此屏失败，下面是timing参数，不知是否有错？
屏文件
/*
* RockChip. N156HGE_LCD_1920x1080
*
*/
/ {
disp_timings: display-timings {
native-mode = <&timing0>;
timing0: timing0 {
screen-type = <SCREEN_EDP>;
out-face = <OUT_P666>;
clock-frequency = <138000000>;
hactive = <1920>;
vactive = <1080>;
hback-porch = <5>;
hfront-porch = <160>;
vback-porch = <9>;
vfront-porch = <32>;
hsync-len = <2>;
vsync-len = <1>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <1>;
swap-rb = <0>;
swap-rg = <0>;
swap-gb = <0>;
};
};
};
