This is a second attempt at honering the country code send out by access
points. This was first added in commit b0b524f079 ("brcmfmac: use
ISO3166 country code and 0 rev as fallback").
Subsequently this was reverted in commit 151a7c12c4 ("Revert "brcmfmac:
use ISO3166 country code and 0 rev as fallback""), because it was causing
issues with AP mode on some brcmfmac models (specifically on BCM4359/9).
Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are
all special world-wide compatibility ccode-s. Most of these world-wide
ccode-s allow passive scan mode only for 2.4GHz channels 12-14,
only enabling them when an AP is seen on them.
But at least on brcmfmac43455 devices this is not working correctly, these
do not see accesspoints on channels 12-14 unless the ccode is changes to
a country where these channels are allowed.
Translating received country codes to an ISO3166 country code and 0 rev
ccreq fixes devices using a brcmfmac43455 with a X2/XT/XU/XV/ALL ccode
not seeing accesspoints on channels 12-14.
To avoid this causing issues on other brcmfmac models again, the
fallback is limited to only brcmfmac4345* chips this time.

The call to brcm_alt_fw_path in brcmf_fw_get_firmwares is not protected
by a check to the validity of the fwctx->req->board_type pointer. This
results in a crash in strlcat when, for example, the WLAN chip is found
in a USB dongle.
Prevent the crash by adding the necessary check.

This is now the only driver that selects the LEDS_CLASS framework,
which is normally user-selectable. While it doesn't strictly cause
a bug, rework the Kconfig logic to be more consistent with what
other drivers do, and only enable LED support in brcmsmac if the
dependencies are all there, rather than using 'select' to enable
what it needs.

When entering suspend as a client station with wowlan enabled,
the Wi-Fi link is supposed to be maintained. In that state, no
more data is generated from client side, and the link stays idle
as long the station is suspended and as long the AP as no data to
transmit.
However, most of the APs kick-off such 'inactive' stations after
few minutes, causing unexpected disconnect (reconnect, etc...).
The usual way to prevent this is to submit a Null function frame
periodically as a keep-alive. This is something that can be host
/software generated (e.g. wpa_supplicant), but that needs to be
offloaded to the Wi-Fi controller in case of suspended host.
This change enables firmware generated keep-alive frames when
entering wowlan suspend, using the 'mkeep_alive' IOVAR.

The problem is that "channel" is an unsigned int, when it's less 5 the
value of "channel - 5" is not a negative number as one would expect but
is very high positive value instead.
This means that "start" becomes a very high positive value. The result
of that is that we never enter the "for (i = start; i <= end; i++) {"
loop. Instead of storing the result from b43legacy_radio_aci_detect()
it just uses zero.

This reverts commit b0b524f079.
Commit b0b524f079 ("brcmfmac: use ISO3166 country code and 0 rev
as fallback") changes country setup to directly use ISO3166 country
codes if no more specific code is configured. This was done under
the assumption that brcmfmac firmwares can handle such simple
direct mapping from country codes to firmware ccode values.
Unfortunately this is not true for all chipset/firmware combinations.
E.g. BCM4359/9 devices stop working as access point with this change,
so revert the offending commit to avoid the regression.

When resuming from suspend, brcmf_pcie_pm_leave_D3 will first attempt a
hot resume and then fall back to removing the PCI device and then
reprobing. If this probe fails, the kernel will oops, because brcmf_err,
which is called to report the failure will dereference the stale bus
pointer. Open code and use the default bus-less brcmf_err to avoid this.

The patch that would first try the board-specific firmware
had a bug because the fallback would not be called: the
asynchronous interface is used meaning request_firmware_nowait()
returns 0 immediately.
Harden the firmware loading like this:
- If we cannot build an alt_path (like if no board_type is
specified) just request the first firmware without any
suffix, like in the past.
- If the lookup of a board specific firmware fails, we get
a NULL fw in the async callback, so just try again without
the alt_path from a dedicated brcm_fw_request_done_alt_path
callback.
- Drop the unnecessary prototype of brcm_fw_request_done.
- Added MODULE_FIRMWARE match for per-board SDIO bins, making
userspace tools to pull all the relevant firmware files.

After some crashes in the 3D engine (!) on the Samsung GT-I8530
it turns out that the main firmware file can be device dependent,
something that was previously only handled for the NVRAM
parameter file.
Rewrite the code a bit so we can a per-board suffixed firmware
binary as well, if this does not exist we fall back to the
canonical firmware name.
Example: a 4330 device with the OF board compatible is
"samsung,gavini". We will first try
"brcmfmac4330-sdio.samsung,gavini.bin" then "brcmfmac4330-sdio.bin"
if that does not work.

With any regulatory domain requests coming from either user space or
802.11 IE (Information Element), the country is coded in ISO3166
standard. It needs to be translated to firmware country code and
revision with the mapping info in settings->country_codes table.
Support populate country_codes table by parsing the mapping from DT.
The BRCMF_BUSTYPE_SDIO bus_type check gets separated from general DT
validation, so that country code can be handled as general part rather
than SDIO bus specific one.

KMSG is flooded with error messages about unsupported firmware
features of BCM4329 chip. The GET_ASSOCLIST error became especially
noisy with a newer NetworkManager version of Ubuntu 21.04. Turn the
noisy error messages into info messages and print them out only once.

The parameter passed to ai_detach() is guaranteed to never be NULL
because it is checked by the caller. Consequently, the result of
container_of() on it is also never NULL, and a NULL check on it
is unnecessary. Even without that, the NULL check would still be
unnecessary because the subsequent kfree() can handle NULL arguments.
On top of all that, it is misleading to check the result of container_of()
against NULL because the position of the contained element could change,
which would make the check invalid. Remove it.
This change was made automatically with the following Coccinelle script.

A static analyzer identified as a potential bug the copy of
12 bytes from a 6 bytes array to a 6 bytes array. Both
arrays are 6 bytes addresses.
Although not being a real bug, it is not immediately clear
why is done this way: next 6 bytes address, contiguous to
the first one, must also be copied to next contiguous 6 bytes
address of the destination.
Copying each one separately will make both static analyzers
and reviewers happier.

Cypress Wi-Fi chipsets include information regarding regulatory
constraints. These are provided to the driver through "Country Local
Matrix" (CLM) blobs. Files present in Linux firmware repository are
on a generic world-wide safe version with conservative power
settings which is designed to comply with regulatory but may not
provide best performance on all boards. Never the less, a better
functionality can be expected with the file present, so add it to the
modinfo of the driver.

Instead of aborting country code setup in firmware, use ISO3166 country
code and 0 rev as fallback, when country_codes mapping table is not
configured. This fallback saves the country_codes table setup for recent
brcmfmac chipsets/firmwares, which just use ISO3166 code and require no
revision number.

These TODO empty code are added by
commit 9442e5b58e ("b43: N-PHY: partly implement SPUR workaround"). It's
been more than a decade now. I don't think anyone who wants to perfect
this workaround can follow this TODO tip exactly. Instead, it limits them
to new thinking. Remove it will be better.
No functional change.
By the way, this helps reduce some binary code size.

There is no need to keep around the dentry pointers for the debugfs
files as they will all be automatically removed when the subdir is
removed. So save the space and logic involved in keeping them around by
just getting rid of them entirely.
By doing this change, we remove one of the last in-kernel user that was
storing the result of debugfs_create_bool(), so that api can be cleaned
up.
