imx6q with wf111 wifi module

[aydogmus]

Hi,

I am trying to work with wf111 silabs on imx6q. I have made some changes over dts file and kernel configs. I also added wf111-linux-driver_5.2.2-r2_armv7-a to yocto, it compiles module into /lib/modules/4.1.36-fslc\+g2fa70a9/extra/unifi_sdio.ko and it does not auto load.

my kconfig changes are:

CONFIG_BT_ATH3K=y
# CONFIG_AF_RXRPC is not set
CONFIG_WIRELESS=y

and my device tree changes are pinctls and :

- bcmdhd_wlan_0: bcmdhd_wlan@0 {
- compatible = "android,bcmdhd_wlan";
+ wf111: wf111@0 {
+ compatible = "unifi_sdio,unifi";
wlreg_on-supply = <&wlreg_on>;
+ status = "okay";
};
}; 

I am not sure about compatible keywords.

end of these operations, I get dmesg entries :

and ifconfig wlan0 gives no interface found error.

Hello Abdulaziz Aydoğmuş,

I think the following thread may be of help since it shows how to add the driver using a Yocto layer with the driver available at a git repository.

I have already added driver to my image, I think my problem is more related to the device tree. Because part 8.4 in https://www.silabs.com/documents/login/application-notes/AN996.pdf document  describes my stuation.
