atheros无线驱动移植问题请教

JIANGXIN04211

最近移植一款无线网卡，公司之前的无线网卡型号是AR9287，只支持2.4G。公司想支持5G，所以选择了一个款支持5G的无线网卡AR9280，直接替换以后发现有如此打印，pci驱动和设备已经匹配成功，并调用了相应的probe函数，在函数__ath_attach错误退出，直接原因在写rtc reset寄存器(7040)后未生效，导致读rtc状态寄存器(7044)时退出，打印ath_dev_attach: unable to attach hardware; HAL status 3。有哪位仁兄遇到过类似的问题？

    你说是要升级整个内核版本吗？还是只升级ath9k驱动。目前公司的内核版本是2.6.32.11，并且更改了很多东西，如果更换整个内核版本几乎是不可能。

是不是RTC的问题？
