调试RK3288 5.10版本内核发现，RK提供的代码dts中未定义lvds_panel，但却在其它地方进行引用修改，不晓得是不是官方提交代码时遗漏了。所以添加lvds_panel定义如下：

	lvds_panel: lvds-panel {status = "disabled";ports {#address-cells = <1>;#size-cells = <0>;port@0 {reg = <0>;panel_in_lvds: endpoint {remote-endpoint = <&lvds_out_panel>;};};};};

并修改lvds_panel内容如下：

&lvds_panel {status = "okay";compatible ="simple-panel";backlight = <&backlight>;power-supply = <&vcc_lvds>;
//     enable-gpios = <&gpio7 4 GPIO_ACTIVE_HIGH>;enable-delay-ms = <20>;prepare-delay-ms = <20>;unprepare-delay-ms = <20>;disable-delay-ms = <20>;/** MEDIA_BUS_FMT_RGB666_1X7X3_SPWG  - "jeida-18"* MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA - "jeida-24"* MEDIA_BUS_FMT_RGB888_1X7X4_SPWG  - "vesa-24"*/bus-format = <MEDIA_BUS_FMT_RGB888_1X7X4_SPWG>;width-mm = <217>;height-mm = <136>;display-timings {native-mode = <&timing0>;timing0: timing0 {clock-frequency = <74250000>;hactive = <1920>;vactive = <1080>;hback-porch = <80>;hfront-porch = <40>;vback-porch = <25>;vfront-porch = <10>;hsync-len = <20>;vsync-len = <10>;hsync-active = <0>;vsync-active = <0>;de-active = <0>;pixelclk-active = <0>;};};
};

其它相关DTS配置按正常套路使能即可。但是重新编译内核烧写后，发现仅在启动时uboot logo可正常显示，后面就在无法点亮屏幕。出现该问题的原因是内核中关闭了"drivers/phy/rockchip/phy-rockchip-inno-video-phy.c"驱动，需要将其编译到内核即可，需要添加如下patch：

下面patch解决编译报错。

diff --git a/drivers/phy/rockchip/phy-rockchip-inno-video-phy.c b/drivers/phy/rockchip/phy-rockchip-inno-video-phy.c

最后’make menuconfig’中勾选’CONFIG_PHY_ROCKCHIP_INNO_VIDEO_PHY’，重新编译烧写后lvds显示正常。
