RK3288[android 7.1]调试笔记 ----双屏同显（edp屏做主屏，lvds做副屏）

1 找到 在要编译的rk3288-evb-android-rk808-edp.dts
调试思路先将edp和lvds屏配置其dts分别点亮后，最后将两个屏的dts合在一起
在rk3288-evb-android-rk808-edp.dts中加上最终的edp屏和lvds屏的dts配置如下：
 

。。。。。。。。。。。
// added for edp start <<<
&edp {
	status = "okay";
};

&edp_phy {
	status = "okay";
};
 &route_edp {
	status = "okay";
};
//rk3288 有两路通道vopb(4K) vopl(2K) ,这里同显设vopb通道是edp,vopl通道是lvds
&edp_in_vopb {
	status = "okay";
};
&edp_in_vopl {
	status = "disabled";
};
&edp_panel {
//	compatible = "simple-panel";
    compatible ="lg,lp079qx1-sp0v";
//	backlight = <&backlight>;  //这里同显如果共用背光，只需要配置一个背光
	power-supply = <&vcc_lcd>;
	status = "okay";

	disp_timings: display-timings {
		native-mode = <&edp_panel_name>;

		edp_panel_name: timing0 {
			clock-frequency = <158000000>;

		};
	};
