        Thank you for your timely response. We have successfully configured the dts file and the kernel now recognizes the Wi-Fi module as an SDIO device. Despite this progress, we encounter an issue where we are unable to establish communication with the device and bring the network interface up; our attempts have been unsuccessful. Upon examining the SDIO lines, we observed communication activity, but we remain uncertain if the Wi-Fi module is responding appropriately. While we suspect driver issues may be at play, the installed drivers (wlcore, wlcore_sdio, and wl18xx along with supplemental drivers) should theoretically support our setup. Could there be any other underlying reasons contributing to our difficulty? Attached for your review is a relevant kernel log.
