Dear all,
I would like to install AP6236 Wi-Fi module via SDIO interface to my iMX6ULL EVK. The console shows some errors after I insmod bcmdhd.ko such as follows.

Then I refer to the AP6236 user guide and it shows there are two GPIO pins must be setup to WL_REG_ON and WL_HOST_WAKE.
What are the numbers of these two GPIOs?
