RK3288 Android7.1 LVDS问题

Chip Platform Rockchip
1

刚接触RK平台，这屏是双路lvds vesa 8bit RGB888，在MTK平台点亮过，我在rk3288-evb-android-rk808-lvds.dts下面的lvds修改

&lvds_panel {
    status = "okay";
    compatible ="simple-panel";
    //backlight = <&backlight>;
    bus-format = <MEDIA_BUS_FMT_RGB888_1X24>;
    power-supply = <&vcc_lcd>;
    enable-gpios = <&gpio7 4 GPIO_ACTIVE_HIGH>;

在system.prop修改

sys.hwc.device.primary=LVDS
#sys.hwc.device.primary=DSI,HDMI-A,LVDS
#sys.hwc.device.extend=LVDS

烧录进去，有背光，屏幕一直白红绿蓝四种颜色不断切换,如果是时序不对，dts里哪些参数是设置时序的。

补充：上面显示不全，补上
&lvds_panel {
status = “okay”;
compatible =“simple-panel”;
//backlight = <&backlight>;
bus-format = <MEDIA_BUS_FMT_RGB888_1X24>;
power-supply = <&vcc_lcd>;
delay,disable = <10>;
enable-gpios = <&gpio7 4 GPIO_ACTIVE_HIGH>;
//rockchip,data-mapping = “jeida”;
rockchip,data-mapping = “vesa”;
rockchip,data-width = <24>;
rockchip,output = “duallvds”;

display-timings {
    native-mode = <&timing0>;
timing0: timing0 {
            clock-frequency = <148000000>;
            hactive = <1920>;             /* Horizontal display area thd 1024       DCLK            */
            vactive = <1080>;             /* Vertical display area tvd   600        H               */

            de-active = <0>;

    };
};

请给出完整的 rk3288-evb-android-rk808-lvds.dts，为什么我的android 7 没有这个文件。我是在 rk3288-firefly-reload.dts 这个基础上修改的
