RK3288 Android11 RTL8723DS WiFi 和 蓝牙Bluetooth 适配

  瑞芯微RK系列对“REALTEK瑞昱公司”的wifi、蓝牙双模的模组都有内置适配的，因此HAL层、Framework层、协议栈及库文件都不需要移植适配，只需修改设备树和一些配置文件即可。

一、RTL8723DS WiFi 适配 — 篇章

1、原理图分析（WiFi部分）

补充:RTL8723DS时钟输入源讲解

  RTL8723DS模组的第24号引脚是模组的时钟输入源，需要给此提供1.8V~3.3V，32KHz的输入源。由原理图可知，提供时钟输入源的是RK808 CLK32KOUT1引脚提供的外部32KHz时钟。因此需要添加：

clocks =<&rk808 1>;
clock-name = "ext_clock";

2、根据原理图修改设备树和编辑驱动文件

  由原理图可以看出，板子上使用的RTL8723DS模块WIFI部分的接口是SDIO接口的，因此在设备树上修改对应的GPIO即可。
  Ⅰ、首先打开对RTL8723DS模块的供电，也就是WL_ON引脚->GPIO8_A4，先需要使用pinctrl将其复用成GPIO功能，然后将其WL_ON引脚拉低电平，让其P-MOS管导通，处理方法如下图所示：


  我这在HD_gpio_control.c这个GPIO驱动程序上初始化GPIO8_A4，默认拉低电平，如下图所示，这里随意写个驱动即可。

  Ⅱ、修改sdio0设备树节点，如下图所示：





  将RTL8723DS驱动添加到内核吗，如下图所示：



  Ⅳ、修改make menuconfig，如下图所示：

3、实验验证

  通过以上配置，基本驱动移植就配置好了，如下图所示：

二、RTL8723DS 蓝牙Bluetooth 适配 — 篇章

1、原理图分析（蓝牙Bluetooth部分）

  上图黄色框框就是本次蓝牙功能适配需要关注的引脚接口。

2、根据原理图修改设备树

3、修改蓝牙相关的配置
