20251118给荣品RD-RK3588的开发板适配USB的HUB芯片FE2_QFP48
2025/11/17 20:58

缘起：经过反复测试，终于把全部的USB接口都点亮USB接口的鼠标了！

当你把荣品RD-RK3588开发板重新适配一把，就相当于从头做了一个项目：【荣品RD-RK3588开发板】。
当然，开发板的功能都是好的，你免除了调试的过程，也就没有解决相关硬件出错的经验/机会了！

结论：荣品的FAE工程师是真的很忙。
代码写的非常写意/潇洒！
【整个DTS，TAB和空格按键都是混用的！^_有些时候看着很难受的！^_】
DTS中的代码排版真的让人看得很难受！

1、很容易/根据经验/看原理图即可知道：USB的HUB芯片FE2_QFP48 的 XRSTJ引脚由GMAC1_TXER/GPIO3_B2_d ，也就是GPIO106控制！

2、DTS

RK3588开发板USB Hub适配DTS配置
给荣品RD-RK3588的开发板的USB hub适配，这个DTS改如何适配呢？

usb-hub-reset {
gpio_num = <&gpio3 RK_PB2 GPIO_ACTIVE_HIGH>;
gpio_function = <4>;
};

根据您提供的代码片段，这看起来是一个USB Hub复位控制的DTS配置。对于荣品RD-RK3588开发板，您需要将这段配置集成到正确的DTS文件中。以下是完整的适配方案：

方法一：在设备树中直接定义USB Hub复位节点
dts
// 在 &gpio3 节点后添加以下配置
&gpio3 {
status = "okay";
};

// 添加USB Hub复位控制器
usb_hub_reset: usb-hub-reset {
compatible = "usb-hub-reset-gpio";
gpios = <&gpio3 RK_PB2 GPIO_ACTIVE_HIGH>;
reset-duration-us = <10000>; // 复位持续时间，单位微秒
// 可选的初始化延迟
initial-reset-delay-us = <100000>;
status = "okay";
};

4、使用了DeepSeek推荐的写法，是否可以直接使用荣品的写法请自行验证了！^_

5、查看GPIO口复用可以很容易看见GPIO口冲突了！
