Infineon(Cypress) is introducing a new INFFMAC (WLAN FULLMAC) Linux driver
specifically for its new-generation AIROC family of Wi-Fi Connectivity
Processor (CP) chipsets (CYW5591x), Wi-Fi + Bluetooth combo chipsets
(CYW5557x, CYW5551x, CYW5591x, CYW43022), and also for all future chipsets.
The chipsets from these families have various combinations of capabilities
like Wi-Fi 6/5, 2.4/5/6GHz, 1x1/2x2, 20/40/80MHz and PCIe/SDIO BUS, etc.
Infineon's full list of Wireless Connectivity product briefs and datasheets
are available in https://www.infineon.com/products/wireless-connectivity
The Infineon chipsets listed above are tailor-made for a wide variety of
IoT use cases and provide support for multiple host BUS interfaces
(eventually gSPI, SPI, I2C, USB, and UART support will be added
in future contributions). In addition, these new chipsets support IoT mode
of operations that require an Infineon-proprietary secured Device firmware
architecture.
By default, this driver expects the device firmware/image/NVRAM/CLM_BLOB
files in the filesystem path /lib/firmware/infineon/ with the file name
prefix “inffmac*” (for example: inffmac43022-sdio.trxs). This driver is
tested for AP, STA, and P2P operation modes on Intel NUC platform.
As suggested in the review comments received on V1, had to reduce the size
of the driver, so removed some major functionalities, to be added later.
Also have split the driver into smaller commits to make the review easier,
Final version would be a single commit for the inffmac driver changes.
Kindly let us know if there is anything else that we can do to help with
the review. Completed checkpatch verification with current default max
line length (100) used in linux. If checkpatch is ran with a line
length restriction of 80 characters, then we can expect some warnings.
More information on this driver is available in V1 cover letter [1].

v2:
- Improved support for Infineon's new type of WLAN chipsets having the
the Connectivity Processor (CP) architecture which provides wireless
connectivity along with a host network offload. The driver communicates
with various components (like, CP, WLAN FW) inside these devices using
the ICDC protocol over the SDIO BUS.
- Fully refactored the interface management functionality and added the
Dynamic vif creation, deletion support.
- Separated out the P2P functionality from the Management Frame TX
functionality.
- Improved the Device Firmware Update (DFU) support to update the Firmware
over SDIO in Device FLASH Memory or PSRAM during runtime.
- Started utilizing wiphy locking, wiphy work and wiphy delayed work
scheduling infrastrucutre provided by cfg80211 for the WLAN Drivers.
- Cleaned up multiple source and header files.
- Skipped support for WLAN Sensing, XDP, Packet offloads now, to be added
later in a separate patch with a dedicated review, as suggested in v1.
- Also skipped the support for BT Coexistance, Shared SDIO for BT, PNO,
Debug Logger, most of the module params, etc now to shrink the driver
size in this version to help with the review.
