RK 方案VOP 显示接口的链接关系以及DTS如何配置

这图显示各vp 支持情况 如下图VP0 支持DSI0 DSI1 EDP LVDS HDMI 显示接口，如果我们一方案需要点MIPI 屏 和HDMI out, 如果VP0 链接MIPI DSI0 那么VP0 就不能再选择了，只能VP1 链接HDMI out 了。因为VP2不至此HDMI，所有就只有选择VP1 链接HDMI

 vop: vop@fe040000 {compatible = "rockchip,rk3568-vop";reg = <0x0 0xfe040000 0x0 0x3000>, <0x0 0xfe044000 0x0 0x1000>;reg-names = "regs", "gamma_lut";rockchip,grf = <&grf>;interrupts = <0 148 4>;clocks = <&cru 221>, <&cru 222>, <&cru 223>, <&cru 224>, <&cru 225>;clock-names = "aclk_vop", "hclk_vop", "dclk_vp0", "dclk_vp1", "dclk_vp2";iommus = <&vop_mmu>;power-domains = <&power 9>;status = "disabled";vop_out: ports {#address-cells = <1>;#size-cells = <0>;vp0: port@0 {#address-cells = <1>;#size-cells = <0>;reg = <0>;vp0_out_dsi0: endpoint@0 {reg = <0>;remote-endpoint = <&dsi0_in_vp0>;};vp0_out_dsi1: endpoint@1 {reg = <1>;remote-endpoint = <&dsi1_in_vp0>;};vp0_out_edp: endpoint@2 {reg = <2>;remote-endpoint = <&edp_in_vp0>;};vp0_out_hdmi: endpoint@3 {reg = <3>;remote-endpoint = <&hdmi_in_vp0>;};};vp1: port@1 {#address-cells = <1>;#size-cells = <0>;reg = <1>;vp1_out_dsi0: endpoint@0 {reg = <0>;remote-endpoint = <&dsi0_in_vp1>;};vp1_out_dsi1: endpoint@1 {reg = <1>;remote-endpoint = <&dsi1_in_vp1>;};vp1_out_edp: endpoint@2 {reg = <2>;remote-endpoint = <&edp_in_vp1>;};vp1_out_hdmi: endpoint@3 {reg = <3>;remote-endpoint = <&hdmi_in_vp1>;};vp1_out_lvds: endpoint@4 {reg = <4>;remote-endpoint = <&lvds_in_vp1>;};};vp2: port@2 {#address-cells = <1>;#size-cells = <0>;reg = <2>;vp2_out_lvds: endpoint@0 {reg = <0>;remote-endpoint = <&lvds_in_vp2>;};vp2_out_rgb: endpoint@1 {reg = <1>;remote-endpoint = <&rgb_in_vp2>;};};};};

DTS 配置如下 ，hdmi_in_vp1 / dsi0_in_vp0打开
