TI中文支持网在AM335X上安装了所有的驱动，iw wlan0 scan 失败，一直阻塞在那。
[ 113.746368] D:mac80211 hw scan（启动内核打印使能打印这句然后就一直阻塞在这里了）
以下分别是安装驱动启动的log，ifconfig wlan0 up 的log，以及ifconfig 出现的wlan0 相关节点信息。
说明：我们的硬件，wl1807 接到AM335X的过程中有经过一个反向器，所以AM335X这边中断引脚的电平刚好和wl1807出来的电平相反，这在驱动中是否有关系，如果有，需要在哪里修改，我们用的linux内核是3.14版本，设备树启动？
这是安装驱动启动的log

hi,
其实也不用修改源码，修改设备树更简单点，个人觉得。修改设备树如下：
&mmc3 { status = "okay"; vmmc-supply = <&wlan_en_reg>; bus-width = <4>; pinctrl-names = "default", "sleep"; pinctrl-0 = <&mmc3_pins_default &wlan_pins_default>; pinctrl-1 = <&mmc3_pins_sleep &wlan_pins_sleep>; ti,non-removable; ti,needs-special-hs-handling; cap-power-off-card; keep-power-in-suspend;
#address-cells = <1>; #size-cells = <0>; wlcore: wlcore@0 { compatible = "ti,wl1835"; reg = <2>; interrupt-parent = <&gpio3>; interrupts = <17 IRQ_TYPE_LEVEL_LOW>; };};
