原先的13.3的LG屏替換成，BOE的13.3的屏，

只需要在DTS中原先的屏參數改為，要調換的屏參數。

&edp_panel {
?? ?compatible ="lg,lp079qx1-sp0v", "simple-panel";
?? ?backlight = <&backlight>;
?? ?enable-gpios = <&gpio6 11 GPIO_ACTIVE_HIGH>;
?? ?enable-delay-ms = <60>;//120 150 200 80
?? ?pinctrl-0 = <&lcd_cs>;
?? ?power-supply = <&vcc_lcd>;
?? ?status = "okay";
?
?? ?disp_timings: display-timings {
?? ??? ?native-mode = <&timing0>;

?? ??? ?timing0: timing0 {
?? ??? ??? ?clock-frequency = <148500000>; //180000000
?? ??? ??? ?
?? ??? ??? ?hactive = <1920>;
?? ??? ??? ?hfront-porch = <48>;
?? ??? ??? ?hsync-len = <32>;
?? ??? ??? ?hback-porch = <200>; //80
?? ??? ??? ?hsync-active = <0>;
?? ??? ??? ?
?? ??? ??? ?
?? ??? ??? ?vactive = <1080>;
?? ??? ??? ?vfront-porch = <3>;
?? ??? ??? ?vsync-len = <6>; //5
?? ??? ??? ?vback-porch = <31>; //23
?? ??? ??? ?vsync-active = <0>;
?? ??? ??? ??
?? ??? ??? ?de-active = <0>;
?? ??? ??? ?pixelclk-active = <0>;
?? ??? ?};
?? ?};
};

這樣只是改了最終的傳遞參數，其實好多中間并沒有利用上，之前做過一些嘗試，比如說在kernel/drivers/gpu/drm/panel/panel-simple.c中加上了相應的BOE屏的函數、結構體，并在DTS的compatible中把LG的驅動改成了BOEde

以下是LG的屏原先的參數。

&edp_panel {
?? ?compatible ="lg,lp079qx1-sp0v", "simple-panel";
?? ?backlight = <&backlight>;
?? ?enable-gpios = <&gpio6 11 GPIO_ACTIVE_HIGH>;
?? ?enable-delay-ms = <120>;//120 150 200 80
?? ?pinctrl-0 = <&lcd_cs>;
?? ?power-supply = <&vcc_lcd>;
?? ?status = "okay";
?
?? ?disp_timings: display-timings {
?? ??? ?native-mode = <&timing0>;

?? ??? ?timing0: timing0 {
?? ??? ??? ?clock-frequency = <180000000>; //180000000 148500000
?? ??? ??? ?
?? ??? ??? ?hactive = <1920>;
?? ??? ??? ?hfront-porch = <48>;
?? ??? ??? ?hsync-len = <32>;
?? ??? ??? ?hback-porch = <80>; //80 200
?? ??? ??? ?hsync-active = <0>;
?? ??? ??? ?
?? ??? ??? ?
?? ??? ??? ?vactive = <1080>;
?? ??? ??? ?vfront-porch = <3>;
?? ??? ??? ?vsync-len = <5>; //5 6
?? ??? ??? ?vback-porch = <23>; //23 31
?? ??? ??? ?vsync-active = <0>;
?? ??? ??? ??
?? ??? ??? ?de-active = <0>;
?? ??? ??? ?pixelclk-active = <0>;
?? ??? ?};
?? ?};
};
