WILC3000-SDIO initialization error
Similar as in previous issue, wilc3000 connected to sdio0 interface of sama5d27-som1 based board...
Device tree binding:
sdmmc0: sdio-host@a0000000 {

pinctrl-0 = <&pinctrl_sdmmc0_default>;

chip_en-gpios = <&pioA PIN_PA25 GPIO_ACTIVE_HIGH>;
reset-gpios = <&pioA PIN_PA26 GPIO_ACTIVE_LOW>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_wilc3000_default>;
status = "okay"; /* Conflict with wilc-spi */
bus-width = <4>;
reg = <0>;
};
};

};
};
pinctrl_sdmmc0_default: sdmmc0_default {

After system startup so far so good:

Update:
There is one possible workaround:
Device seem to be working if I comment out
reset-gpios = <&pioA PIN_PA26 GPIO_ACTIVE_LOW>;
Tried that, same output:

Hello, I noticed that sama5d27-som1-ek has strange behavior on startup. EN and RESET pins go up when the power is applied. This actually happens on all GPIO pins that i checked out. If I manually put them back to zero before loading wilc_sdio module to kernel i see correct power up sequence on oscilloscope, but module wont start. I suspect that this causes the problem on startup.
If you put the GPIOs low before inserting the kernel module, the SDIO probe function in the driver will not be called since the SDIO device (WILC) is powered down and won't respond to SDIO probes, and hence, the driver won't initialize since the probe function is the initialization point for the driver.
How's the WILC3000 SDIO board connected to the SOM? I'm suspecting it might be a problem with the SDIO Dat lines since in your original logs it seems like it's probing correctly, but fails afterwards.
We are using module, not WILC3000 SDIO board. Module is connected to mmc0 interface directly and we also have EN, INT and RESETN lines connected to the PA24, PA25 and PA26. Moreover, EN and RESETN are pulled down through 1M resistors.
