平台:全志A33 Android4.4
模块：RTL8723DS
接口：SDIO、uart1（ttyS1）
kernel：Linux3.4
一、 移植8723ds驱动，让驱动参与编译
1.将rtl8723ds驱动源码放到linux-3.4/drivers/net/wireless/目录下，并生成一个rtl8723ds目录
驱动下载地址:https://download.csdn.net/download/Mrdeath/13744931
注意：该驱动不是原版驱动，而是经过了我的修改去适配了A33 Android4.4的SDK，由于A33源码里面并没有8723ds的源码，所以sys_config.fex,以及rf目录下没有针对8723ds的电源控制，所以如果你是完全参考我方案来移植，请务必使用该版驱动。
2.修改配置文件添让驱动参与编译：
(1).修改Kconfig文件
--git a/lichee/linux-3.4/drivers/net/wireless/Kconfig b/lichee/linux-3.4/drivers/net/wireless/Kconfig
index 33409594d0..0055f4567c 100755

配置完上面内容后，rtl8723ds驱动就能正确参与编译了。
二、 配置系统开机自动加载8723ds驱动
1.修改BoardConfig.mk
SW_BOARD_USR_WIFI、BOARD_WLAN_DEVICE、SW_BOARD_HAVE_BLUETOOTH_NAME值改为8723ds
diff --git a/android4.4/device/softwinner/astar-y3/BoardConfig.mk b/android4.4/device/softwinner/astar-y3/BoardConfig.mk

上面添加完之后，系统开机后就能自动加载8723.ko驱动，具体的加载流程我就不描述了。这里简单说下加载ko文件是在hardware/libhardware_legacy/wifi/wifi.c下的int wifi_load_driver() 加载对应的wifi驱动
三、添加fw和config固件
1.修改astar_y3.mk

+++ b/android4.4/device/softwinner/astar-y3/astar_y3.mk

目录名字重命名为rtl8723ds
包下载地址:https://download.csdn.net/download/Mrdeath/13745180
注意：如果你的bt使用的接口不是ttyS1，请修改hardware/realtek/bluetooth/rtl8723ds/libbt-vendor/include/vnd_astar-y3.txt文件下的BLUETOOTH_UART_DEVICE_PORT = "/dev/ttyS*"
四、配置8723ds参数
1.修改init.sun8i.rc
蓝牙串口改为ttyS1
diff --git a/android4.4/device/softwinner/astar-y3/init.sun8i.rc b/android4.4/device/softwinner/astar-y3/init.sun8i.rc

+ chmod 0666 /dev/ttyS1
+ chown bluetooth net_bt_stack /dev/ttyS1
#
# power up/down interface
chmod 0660 /sys/class/rfkill/rfkill0/state2.修改sys_config文件
在[wifi_para]那一栏，我设置的是8723bs的参数，其实这里我是对8723ds的电源管理参考8723bs进行了修改，所以这些参数同样针对8723ds能使用，所以这几项正常打开配置使用就行。
注意：
wifi_mod_sel必须为5，因为我是根据8723bs的参数修改的8723ds驱动，所以这里mod要选择5
rtl8723bs_lpo_use_apclk为1，我的模块的32k时钟是从cpu引出的，所以我这边设为1，如果你使用的是外部32k时钟，这里设为0
