Subject: Re: Broadcom 43340 module on iMX6DL

Hi Dong,

I tested the kerne 4.0 and the driver works (It loads the driver
correctly, it show's the wlan0 interface and it did not bail out...)

bcrm {
  compatible = "brcm,bcm4329-fmac";
  interrupt-parent = <&gpio3>;
  interrupts = <22 0x2>;
  interrupt-names = "host-wake";
};


Regards,

John
