There is inconsistency in firmware naming for W8997 SDIO wifi chip. Firmware for this chip is stored in linux-firmware [1] repository under filename sdsd8997_combo_v4.bin. But mainline linux kernel driver mwifiex_sdio.ko [2] expects and loads firmware for this chip from filename sd8997_uapsta.bin. So result is that W8997 SDIO wifi chip does not work out of box and people are complaining where to get "sd8997_uapsta.bin" firmware file as it does not exist [3]. People suggest to rename it. Do you have any opinion how to solve this problem? As Marvell is using sdsd8997_combo_v4.bin name for this firmware I would suggest to extend mwifiex_sdio.ko Linux driver to load this firmware also from the file sdsd8997_combo_v4.bin. Also firmware file sdsd8997_combo_v4.bin in linux-firmware git repository [1] is in version 16.68.1.p179. But there is already newer version available (e.g. 16.68.1.p197) . Are you able to update firmware for W8997 SDIO chip in linux-firmware repository to the lasted version?
