[参考译文] PROCESSOR-SDK-AM62P：添加 sn65dsi86 芯片、但 eDP 没有输出

你好、Divyansh Mittal

SDK： ti-processor-sdk-linux-am62xx-evm-10.01.10.04

 我的 DTS 相关 sn65dsi86、如下所示

     dp0: dp0-connector {
                 //compatible = "ti,panel-dp";
		compatible = "dp-connector";
		label = "DP0";
		type = "full-size";
		dp-pwr-supply = <&dp0_pwr_3v3>;
		port {
			dp0_connector_in: endpoint {
				remote-endpoint = <&edp_bridge_out>;
			};
		};
     };
     
     &main_i2c2 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&main_i2c2_pins_default>;
	clock-frequency = <400000>;
	
        bridge_dsi86: bridge@2c {
		compatible = "ti,sn65dsi86";
		reg = <0x2c>;

		enable-gpios = <&main_gpio0 84 GPIO_ACTIVE_HIGH>;
		//suspend-gpios = <&msmgpio 34 GPIO_ACTIVE_LOW>;

		interrupts-extended = <&main_gpio0 83 IRQ_TYPE_EDGE_FALLING>;

		vccio-supply = <&buck3>;
		vcca-supply = <&vdd_sn65_1v2>;
		vpll-supply = <&buck3>;
		vcc-supply = <&vdd_sn65_1v2>;

		clock-names = "refclk";
		clocks = <&edp_refclk>;

		ports {
		  #address-cells = <1>;
		  #size-cells = <0>;

		  port@0 {
		    reg = <0>;

		    edp_bridge_in: endpoint {
		      remote-endpoint = <&dsi0_out>;
		    };
		  };

		  port@1 {
		    reg = <1>;

		    edp_bridge_out: endpoint {
		      data-lanes = <0 1 2 3>;
		      //lane-polarities = <0 0 0 0>;
		      remote-endpoint = <&dp0_connector_in>;
		    };
		  };
		};
	      };	
};

&dss1 {
        bootph-all;
	status = "okay";
};

&dss1_ports {
	#address-cells = <1>;
	#size-cells = <0>;

	/* DSS1-VP1: DSI Output */
	port@1 {
		reg = <1>;

		dss1_dpi1_out: endpoint {
			remote-endpoint = <&dsi0_in>;
		};
	};
};

&dsi0 {
	status = "okay";
	//#address-cells = <1>;
	//#size-cells = <0>;

	ports {
		#address-cells = <1>;
		#size-cells = <0>;

		port@0 {
			reg = <0>;

			dsi0_out: endpoint {
				remote-endpoint = <&edp_bridge_in>;
			};
		};

		port@1 {
			reg = <1>;

			dsi0_in: endpoint {
				remote-endpoint = <&dss1_dpi1_out>;
			};
		};
	};	
};

&dphy_tx0 {
        //compatible = "ti,j721e-dphy";
	status = "okay";
};

似乎所有驱动程序都已连接。但当我运行 kmstest 时、它没有向 DP 发出任何信息。
