For new driver, it should be submitted one file per patch first. Once if accepted, it will become one single patch. That is the reason, I won't give commit message for the patch of a single file.

This series adds support for IW61x which is a new family of 2.4/5 GHz dual-band 1x1 Wi-Fi 6, Bluetooth/Bluetooth Low Energy 5.2 and 15.4 tri-radio single chip by NXP. These devices support 20/40/80MHz single spatial stream in both STA and AP mode. Communication to the IW61x is done via SDIO interface This driver is a derivative of existing Mwifiex [1] and based on similar full-MAC architecture [2]. It has been tested with i.MX8M Mini evaluation kits in both AP and STA mode. All code passes sparse and checkpatch Data sheet (require registration): https://www.nxp.com/products/wireless-connectivity/wi-fi-plus-bluetooth- plus-802-15-4/2-4-5-ghz-dual-band-1x1-wi-fi-6-802-11ax-plus-bluetooth-5- 4-plus-802-15-4-tri-radio-solution:IW612 Known gaps to be addressed in the following patches, - Enable 11ax capabilities. This initial patch support up to 11ac. - Support DFS channel. This initial patch doesn't support DFS channel in both AP/STA mode. This patch is presented as a request for comment with the intention of being made into a patch after initial feedbacks are addressed [1] We had considered adding IW61x to mwifiex driver, however due to FW architecture, host command interface and supported features are significantly different, we have to create the new nxpwifi driver. Subsequent NXP chipsets will be added and sustained in this new driver. [2] Some features, as of now, WPA2/WPA3 personal/enterprise are offloaded to host wpa_supplicant/hostapd.
