20241007给荣品RD-RK3588-AHD开发板刷Rockchip原厂的Buildroot是使用ADB
2024/10/7 17:35

缘起：由于荣品RD-RK3588-AHD开发板使用的是9针的USB-A口，没有使用EVB4默认的type C口。
因此需要拿掉fusb302的驱动/DTS配置部分。
同时，为了简单起见，直接将type C0降级为USB2.0使用了。
【当然要比对荣品RD-RK3588-AHD开发板 linux的SDK中的DTS】
Z:\source\kernel\arch\arm64\boot\dts\rockchip\rk3588\rd-rk3588s-ahd.dts

1、关闭i2c8的usbc0部分：
Z:\rk3588s_20230620\kernel\arch\arm64\boot\dts\rockchip\rk3588s-evb4-lp4x.dtsi
&i2c8 {
   status = "okay";
   pinctrl-names = "default";
   pinctrl-0 = <&i2c8m2_xfer>;

   usbc0: fusb302@22 {
       compatible = "fcs,fusb302";
       reg = <0x22>;
       interrupt-parent = <&gpio0>;
       interrupts = <RK_PC6 IRQ_TYPE_LEVEL_LOW>;
       pinctrl-names = "default";
       pinctrl-0 = <&usbc0_int>;
       vbus-supply = <&vbus5v0_typec>;
       status = "okay";

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

           port@0 {
               reg = <0>;
               usbc0_role_sw: endpoint@0 {
                   remote-endpoint = <&dwc3_0_role_switch>;
               };
           };
       };

       usb_con: connector {
           compatible = "usb-c-connector";
           label = "USB-C";
           data-role = "dual";
           power-role = "dual";
           try-power-role = "sink";
           op-sink-microwatt = <1000000>;
           sink-pdos =
               <PDO_FIXED(5000, 1000, PDO_FIXED_USB_COMM)>;
           source-pdos =
               <PDO_FIXED(5000, 3000, PDO_FIXED_USB_COMM)>;

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

               altmode@0 {
                   reg = <0>;
                   svid = <0xff01>;
                   vdo = <0xffffffff>;
               };
           };

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

               port@0 {
                   reg = <0>;
                   usbc0_orien_sw: endpoint {
                       remote-endpoint = <&usbdp_phy0_orientation_switch>;
                   };
               };

               port@1 {
                   reg = <1>;
                   dp_altmode_mux: endpoint {
                       remote-endpoint = <&usbdp_phy0_dp_altmode_mux>;
                   };
               };
           };
       };
   };

   hym8563: hym8563@51 {
       compatible = "haoyu,hym8563";
       reg = <0x51>;
       #clock-cells = <0>;
       clock-frequency = <32768>;
       clock-output-names = "hym8563";
       pinctrl-names = "default";
       pinctrl-0 = <&hym8563_int>;
       interrupt-parent = <&gpio0>;
       interrupts = <RK_PB0 IRQ_TYPE_LEVEL_LOW>;
       wakeup-source;
       status = "okay";
   };
};

&mipi_dcphy0 {
status = "okay";
};

&mipi_dcphy1 {
status = "disabled";
};

修改为：
&i2c8 {
   status = "okay";
   pinctrl-names = "default";
   pinctrl-0 = <&i2c8m2_xfer>;

   //usbc0: fusb302@22 {

   //           reg = <0>;
   //           usbc0_role_sw: endpoint@0 {
   //               //remote-endpoint = <&dwc3_0_role_switch>;
   //           };
   //       };
   //   };
//
   //   usb_con: connector {
   //       compatible = "usb-c-connector";
   //       label = "USB-C";
   //       data-role = "dual";
   //       power-role = "dual";
   //       try-power-role = "sink";
   //       op-sink-microwatt = <1000000>;
   //       sink-pdos =
   //           <PDO_FIXED(5000, 1000, PDO_FIXED_USB_COMM)>;
   //       source-pdos =
   //           <PDO_FIXED(5000, 3000, PDO_FIXED_USB_COMM)>;
//
   //       altmodes {
   //           #address-cells = <1>;
   //           #size-cells = <0>;
//
   //           altmode@0 {

   //               vdo = <0xffffffff>;
   //           };
   //       };
//
   //       ports {
   //           #address-cells = <1>;
   //           #size-cells = <0>;
//
   //           port@0 {
   //               reg = <0>;
   //               usbc0_orien_sw: endpoint {

   //               };
   //           };
   //       };
   //   };
   //};

&mipi_dcphy0 {
status = "okay";
};

&mipi_dcphy1 {
status = "disabled";
};

2、关闭usbdp_phy0，将EVB4上的type-C0改为USB2.0模式的ADB了。
&uart8 {
   status = "okay";
   pinctrl-names = "default";
   pinctrl-0 = <&uart8m1_xfer &uart8m1_ctsn>;
};

&usbdp_phy0 {
   orientation-switch;
   svid = <0xff01>;
   sbu1-dc-gpios = <&gpio1 RK_PB6 GPIO_ACTIVE_HIGH>;
   sbu2-dc-gpios = <&gpio1 RK_PB7 GPIO_ACTIVE_HIGH>;

   port {
       #address-cells = <1>;
       #size-cells = <0>;
       usbdp_phy0_orientation_switch: endpoint@0 {
           reg = <0>;
           remote-endpoint = <&usbc0_orien_sw>;
       };

       usbdp_phy0_dp_altmode_mux: endpoint@1 {
           reg = <1>;
           remote-endpoint = <&dp_altmode_mux>;
       };
   };
};

&usbdrd_dwc3_0 {
   usb-role-switch;
   port {
       #address-cells = <1>;
       #size-cells = <0>;
       dwc3_0_role_switch: endpoint@0 {
           reg = <0>;
           remote-endpoint = <&usbc0_role_sw>;
       };
   };
};

&usbhost3_0 {
status = "disabled";
};

&usbhost_dwc3_0 {
status = "disabled";
};

修改为：
&uart8 {
   status = "okay";
   pinctrl-names = "default";
   pinctrl-0 = <&uart8m1_xfer &uart8m1_ctsn>;
};

//&usbdp_phy0 {
//   orientation-switch;
//   svid = <0xff01>;
//   sbu1-dc-gpios = <&gpio1 RK_PB6 GPIO_ACTIVE_HIGH>;
//   sbu2-dc-gpios = <&gpio1 RK_PB7 GPIO_ACTIVE_HIGH>;
//
//   port {
//       #address-cells = <1>;
//       #size-cells = <0>;
//       usbdp_phy0_orientation_switch: endpoint@0 {

//           remote-endpoint = <&usbc0_orien_sw>;
//       };
//
//       usbdp_phy0_dp_altmode_mux: endpoint@1 {
//           reg = <1>;

//   };
//};
