Hello,

I think the wfx driver is now mature enough to be accepted in the
drivers/net/wireless directory.

The firmware is now a part of the linux-firmware repository since relase
20210315[1]. It had taken a bit of time because I have worked with the legal
department to simplify the redistribution terms of the firmware.

[1]: https://lore.kernel.org/linux-firmware/2833354.gXvVfaC4I7@pc-42/

As requested by Kalle[2], I send one file per patch. At the end, all the
patches (or at least the patches 3 to 24) will be squashed (therefore, I
didn't bother to write real commit messages).

[2]: https://lore.kernel.org/lkml/87ft6p2n0h.fsf@xxxxxxxxxxxxxx/

Here is a diagram of the global architecture that may help to understand
the code:

Roughly, I have sent the files from the bottom to the top.

v6:
- Rebase on last staging-next (roughtly somewhere after the 5.15
merge window). So, this series include the patches from:
https://lore.kernel.org/netdev/20210913130203.1903622-1-Jerome.Pouiller@xxxxxxxxxx/

v5:
- Add reference to the PR to linux-firmware in the cover letter
- Rebase on last staging tree (that mainly include commit 6efed0a69794
"staging: wfx: fix possible panic with re-queued frames" and a few
cosmetics changes)
- Remove useless trailing spaces in DT binding (Rob)
- Add a commit message in the patch 2 since I am not sure it will be
squashed with the other (Rob)

v4:
- Rebase on last staging tree
- Add 'additionalProperties: false' to the DT specification (I made that
change blindly because I am able to reproduce Rob's error) (Rob)
- Replace C++ comments with Ansi C comments (Kalle)
- Check that existing Ansi C comments comply with net/ "compact" style
- Drop one obsolete comment
- Remove comments after '#endif' in header files
- Remove macro redefinitions in hif_api_general.h (Kalle)
- Replace compiletime_assert() with BUILD_BUG_ON_MSG() (Kalle)
- Rename ieee80211_is_action_back() (Kalle)
- Add a comment explaining how the PDS is sent to the device (Kalle)
- Add a comment about case where CONFIG_MMC==m in the Makefile (Kalle)
- Fix irrevelant comment about CONFIG_VMAP_STACK (Kalle)
- Talk about the unreliable SDIO Vendor ID in the Kconfig help (Kalle)
- Mention the firmware status in the cover letter (Kalle)
- Fix misaligned function arguments in key.c

v3:
- dt-bindings: Rename config-file property (Rob)
- dt-bindings: No additional properties are allowed (spi-max-frequency is
already listed) (Rob)
- dt-bindings: Remove references for mac-address properties (Rob)
- Rebase on staging/staging-next

v2:
- dt-bindings: Improve device description and add link to the datasheet
(Rob)
- dt-bindings: Add blank lines between each DT property (Rob)
- dt-bindings: Explicitly mention mac-address and local-mac-address and
add references to ethernet-controller.yaml (Rob)
- dt-bindings: "config-file" is not for development/debug (Rob)
- dt-bindings: Remove description of "spi-max-frequency" (Rob)
- dt-bindings: Use "folded scalar" syntax instead of escaping the colons
- bus_sdio.c: A compatible node in the DT is now mandatory to probe the
device. Also change documentation of dt-bindings accordingly (Pali,
Ulf)
- bus_sdio.c: Move SDIO IDs to sdio_ids.h (Pali)
- bh.c: Import patch "staging: wfx: fix test on return value of
gpiod_get_value()" (Nathan)
- data_tx.c: Import patch "staging: wfx: fix use of uninitialized
pointer"
- sta.c: Import patch "staging: wfx: make a const array static, makes
object smaller" (Colin)

v1:
- Drop the function name in the warning message (Kalle)
- Replace goto by return in wfx_send_pdata_pds() (Kalle, Dan)
- Improve error label in wfx_send_pdata_pds() (Kalle)
