RK3399 MIPI显示驱动 eDP显示驱动
配置文件:"arch/arm64/boot/dts/rockchip/lcd-edp-for-sunychip-rk3399.dtsi" 如果需要去掉eDP屏，需要在arch/arm64/boot/dts/rockchip/rk3399-sunychip.dtsi中删除include "lcd-edp-for-sunychip.dtsi" 电源控制：enable-gpios= <&gpio4 rk_pd6="" gpio_active_high="">; 原理图： timing时序 1. timing0: timing0 {

eDP信号从vopb输出 1. &edp_in_vopl {

};
&edp_in_vopb {

MIPI初始化命令：一行是一条命令(tab为接上行)； 命令格式：type+命令(没有则为00)+参数数量+参数 timing时序： 1. display-timings {
native-mode = <&timing1>;
iming1: timing1 {
clock-frequency = <64000000>;
hactive = <720>;
vactive = <1280>;
hfront-porch = <40>;
hsync-len = <10>;
hback-porch = <40>;
vfront-porch = <22>;
vsync-len = <4>;
vback-porch = <11>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <0>;
};
};
MIPI信号从vopl输出： 1. &dsi_in_vopl {
status = "okay";
};
&dsi_in_vopb {
status = "disabled";
};
触摸 1. &i2c4 {
status = "okay";
gt1x: gt1x@14 {
status = "okay";
compatible = "goodix,gt1x";
reg = <0x14>;
goodix,rst-gpio = <&gpio4 RK_PC6 GPIO_ACTIVE_LOW>;
goodix,irq-gpio = <&gpio4 RK_PC5 IRQ_TYPE_LEVEL_LOW>;
goodix,enable-gpio = <&gpio4 RK_PD5 GPIO_ACTIVE_HIGH>;
};
};
注意：如果客户需要LVDS需要加TC358775把MIPI转成LVDS。
