RK3588 kernel dts解析之显示模块

Rockchip RK3588 kernel dts解析之显示模块

RK3588 显示模块介绍

RK3588 的VOP (video output process)分为4个Port

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 = <ROCKCHIP_VOP2_ESMART0>;
};
&vp1 {
        rockchip,plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER1 | 1 << ROCKCHIP_VOP2_ESMART1)>;
        rockchip,primary-plane = <ROCKCHIP_VOP2_ESMART1>;
};
&vp2 {
        rockchip,plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER2 | 1 << ROCKCHIP_VOP2_ESMART2)>;
        rockchip,primary-plane = <ROCKCHIP_VOP2_ESMART2>;
};
&vp3 {
        rockchip,plane-mask = <(1 << ROCKCHIP_VOP2_CLUSTER3 | 1 << ROCKCHIP_VOP2_ESMART3)>;
        rockchip,primary-plane = <ROCKCHIP_VOP2_ESMART3>;

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>;

};
//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 {

//使能HDMI1
&hdmi1 {

};
//打开HDMI1 声音
&hdmi1_sound {
        status = "okay";
};
//配置HDMI1上面显示开机logo
