I am trying to use ATWILC3000 wifi with my imx6ul evk board on sdio port. I was able to compile the driver successfully. But the problem is that wifi is not being detected. I made following changes to my dtsi file for wifi module.
{
regulators {
wlreg_on: fixedregulator@100 {
compatible = "regulator-fixed";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-name = "wlreg_on";
/*gpio = <&gpio1 25 0>;*/
startup-delay-us = <100>;
enable-active-high;
};
};
wilc3000_wlan_0: wilc3000_wlan@0 {
compatible = "atmel,wilc_sdio";
wlreg_on-supply = <&wlreg_on>;
};
};
®_sd1_vmmc {
regulator-always-on;
};
&usdhc1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc1 &pinctrl_wifi>;
no-1-8-v;
non-removable;
cd-post;
pm-ignore-notify;
wifi-host;
};
Following message is shown while booting
*** WILC3000 driver VERSION=[14.2.1] ***

Thus I haven't been able to figure where I have made a mistake. Any clues anyone.
