Hello everyone,

This series adds support for CC33xx which is a new family of WLAN IEEE802.11 a/b/g/n/ax
and BLE 5.4 transceivers by Texas Instruments. These devices are 20MHz single spatial stream
enabling STA (IEEE802.11ax) and AP (IEEE802.11n only) roles as well as both roles simultaneously.
Communication to the CC33xx is done via 4-bit SDIO with two extra GPIOs: Enable and Interrupt.

This driver's architecture is a soft-MAC and derivative of existing wl18xx + wlcore code [1].
It has been tested with the AM335x, AM625x, and i.MX8-MP evaluation kits.

Data sheet: https://www.ti.com/lit/gpn/cc3301

All code passes sparse, smatch, coccicheck and checkpatch with very few pragmatic exceptions.

Driver is split on file boundary as required by Linux-wireless wiki:
https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches#new_driver


Change log:
v4:
* Fixed DT compatibility for all CC33xx variants. Improved general formatting
* Refactored sdio.c to better align with other SDIO drivers
* Removed multiple debug traces

v3:
* Added missing sign-offs
* Fixed multiple warnings for memcpy overflow
* Fixed commit message and description of device-tree bindings
Link: https://lore.kernel.org/linux-wireless/[e-mail]/

v2:
* Fixed build bug on non-ARM architectures
* Removed driver version
* Removed trivial debug traces
* Removed debug parameters for cc33xx module
* Fixed multiple type compatibility warnings
* Minor fixes

v1:
* Added dt-bindings
* Removed debugfs to ease review
* Fix build issue with CONFIG_CFG80211_CERTIFICATION_ONUS
* Fix multiple build warnings found with Clang 18 and W=12

[1] It was considered implementing CC33xx as another user of wlcore but The
differences in HW, host interface, IRQ functionality, Rx/Tx behavior and supported features
were too significant so this was abandoned.
