RK3588 显示模块介绍
RK3588 的VOP (video output process)分为4个Port
| port | 分辨率 |
|---|---|
| VP0 | 4K |
| VP1 | 4K |
| VP2 | 4K |
| VP3 | 1080P |
支持8个图层,每个图层可以灵活分配到每个Video Port上
RK3588 支持的显示接口
- 2个DP
- 2个HDMI/eDP 共用接口
- 2个MIPI DSI
- BT656/BT1120
RK3588 开发板EVB1的显示部分硬件设计
显示模块的DTS配置
VOP的配置
arch/arm64/boot/dts/rockchip/rk3588-evb.dtsi
//开启VOP，必须配置
&vop {
status = "okay";
};
&vop_mmu {
status = "okay";
};
//配置VP的图层，这里配置为每个port分别配置2个图层，这里可以根据需求配置，可以把vp0和vp1合并来支持8K显示需求
/* vp0 & vp1 splice for 8K output */
&vp0 {
rockchip,plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER0 | 1 << ROCKCHIP_VOP2_ESMART0)>;
rockchip,primary-plane = ;
};
&vp1 {
rockchip,plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER1 | 1 << ROCKCHIP_VOP2_ESMART1)>;
rockchip,primary-plane = ;
};
&vp2 {
rockchip,plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER2 | 1 << ROCKCHIP_VOP2_ESMART2)>;
rockchip,primary-plane = ;
};
&vp3 {
rockchip,plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER3 | 1 << ROCKCHIP_VOP2_ESMART3)>;
rockchip,primary-plane = ;
};
显示接口配置
HDMI
arch/arm64/boot/dts/rockchip/rk3588-evb1-lp4.dtsi
//使能HDMI0
&hdmi0 {
enable-gpios = <&gpio4 RK_PB1 GPIO_ACTIVE_HIGH>;
status = "okay";
};
//配置HDMI0到VP0上面
&hdmi0_in_vp0 {
status = "okay";
};
//打开HDMI0 声音
&hdmi0_sound {
status = "okay";
};
//配置HDMI0上面显示开机logo
&route_hdmi0 {
status = "okay";
};
//使能HDMI1
&hdmi1 {
enable-gpios = <&gpio4 RK_PB2 GPIO_ACTIVE_HIGH>;
status = "okay";
};
//配置HDMI1到VP1上面
&hdmi1_in_vp1 {
status = "okay";
};
//打开HDMI1 声音
&hdmi1_sound {
status = "okay";
};
//配置HDMI1上面显示开机logo
&route_hdmi1 {
status = "okay";
};
MIPI DSI
arch/arm64/boot/dts/rockchip/rk3588-evb.dtsi
//配置背光，这里主要配置背光使用的pwm口
&backlight {
pwms = <&pwm2 0 25000 0>;
status = "okay";
};
//dsi0接口的mipi屏配置
&dsi0 {
status = "disabled"; //这里默认是disabled，在下一级的rk3588-evb1-lp4.dtsi里面开启，根据实际硬件配置来确认是否打开
//rockchip,lane-rate = <1000>;
//配置mipi屏的参数
dsi0_panel: panel@0 {
status = "okay";
compatible = "simple-panel-dsi";
reg = <0>;
backlight = <&backlight>;
reset-delay-ms = <10>;
enable-delay-ms = <10>;
prepare-delay-ms = <10>;
unprepare-delay-ms = <10>;
disable-delay-ms = <60>;
dsi,flags = <(MIPI_DSI_MODE_VIDEO | MIPI_DSI_MODE_VIDEO_BURST |
MIPI_DSI_MODE_LPM | MIPI_DSI_MODE_EOT_PACKET)>;
dsi,format = ;
