【求助】openwrt15.05 Mt7621 如何配置RGMII,MDC/MDIO，用MDIO控制外挂的SWITCH

snow***

MT7621通过RGMII2外接一个高通的switch QCA8337
如何配置GPIO，使能RGMII、MDC，MDIO，怎么在MDIO总线上读写数据

snow***

顶上去，请大神赐教

板子的DTS文件中pinctrl和ethernet部分的定义如下

1. 
   
2. pinctrl {
   
3.                 state_default: pinctrl0 {
   
4.                         gpio {
   
5.                                 ralink,group = "i2c", "uart2", "uart3";
   
6.                                 ralink,function = "gpio";
   
7.                         };
   
8.                 };
   
9.         };
   
10. ethernet@1e100000 {
    
11.         status = "okay";
    
12. 
    
13.         pinctrl-names = "default";
    
14.         pinctrl-0 = <&rgmii1_pins &rgmii2_pins &mdio_pins>;
    
15. 
    
16.         ralink,port-map = "llllw";
    
17. 
    
18.         port@5 {
    
19.             status = "okay";
    
20.             ralink,fixed-link = <1000 1 1 1>;
    
21.             phy-mode = "rgmii";
    
22.         };
    
23. 
    
24.         mdio-bus {
    
25.             status = "okay";
    
26. 
    
27.             phy0: ethernet-phy@0 {
    
28.                 reg = <0>;
    
29.                 phy-mode = "rgmii";
    
30.                                 qca,ar8327-initvals = <
    
31.                                         0x00004 0x06800000 /* PAD0_MODE */
    
32.                                 >;
    
33.             };
    
34.         };
    
35.     };

下面是启动信息，有看到mdio-bus有探测到了，根据参考网上的帖子，好像还要加载qca8337的驱动，用的是ar8216.ko，但是在menuconfig -- Kernel modules -- Network Devices 里面只有kmod-atl1（Atheros L1 Gigabit Ethernet support）之类的，怎么找到这个驱动。
