Felix Fietkau 33f29d2345 wifi: mt76: relicense to BSD-3-Clause-Clear
MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear,
in order to improve clarity and the legal integrity of the code.

The BSD-3-Clause license includes the "no endorsement" clause, which is
important for protecting the reputation of the original authors and
contributors by preventing unauthorized use of their names for endorsement
purposes.

This clause is absent in the BSD-2-Clause license, which is more permissive
but lacks this specific protection.

This change also cleans up the license of some Kconfig/Makefile files,
which were accidentally marked as GPL.

The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615
for which the license situation still needs to be clarified.

Rosen PenevandFelix Fietkau 9b770cb3da wifi: mt76: mt76_eeprom_override to int
mt76_eeprom_override has of_get_mac_address, which can return
-EPROBE_DEFER if the nvmem driver gets loaded after mt76 for some
reason.

Make sure this gets passed to probe so that nvmem mac overrides always
work.

Henry MartinandFelix Fietkau 87873d854e wifi: mt76: mt7925: Fix null-ptr-deref in mt7925_thermal_init()
devm_kasprintf() returns NULL on error. Currently, mt7925_thermal_init()
does not check for this case, which results in a NULL pointer
dereference.

Add NULL check after devm_kasprintf() to prevent this issue.

Ming Yen HsiehandFelix Fietkau bdc09b8f23 wifi: mt76: mt7925: update the channel usage when the regd domain changed
The 5.9/6GHz channel license of a certain platform device has been
regulated in various countries. That may be difference with standard Liunx
regulatory domain settings. In this case, when .reg_notifier() called for
regulatory change, mt7925 chipset should update the channel usage based on
CLC data.

Ming Yen HsiehandFelix Fietkau 454a69cbb7 wifi: mt76: mt7925: add EHT control support based on the CLC data
Some countries do not support EHT modulation for now. To prevent violating
regulations, the MT7925 chipset should control the EHT capabilities.
Therefore, when a regulatory domain change is detected during scanning,
the `mt7925_regd_be_ctrl` will process the CLC data to update the EHT
capabilities.

Quan ZhouandFelix Fietkau e86e97e453 wifi: mt76: mt7925e: fix too long of wifi resume time
The mt7925e takes a long time to resume in platform resume
scenarios. This is due to the mt7925 reconfiguring the tx
power for each wifi channel during resume. By streamlining
the process and removing redundant power configurations,
the resume time for the mt7925 can be shortened.

Quan ZhouandFelix Fietkau d33ea3cab7 wifi: mt76: mt7925: fix CLC command timeout when suspend/resume
When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.

Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.

Add mt7925, a new mac80211 driver for the MediaTek Wi-Fi 7 (802.11be) device
Filogic 360, which can support Station, AP, P2P, and monitor modes.
Filogic 360 supports max 4096-QAM/160MHz radio operation at 6 GHz, 5 GHz,
or 2.4 GHz with 2x2 antennas. This chip supports PCIe and USB bus type.

mt7925 supports Wi-Fi 6E and EHT rate with single link only at this moment,
whereas Wi-Fi 7 and its specific features are working in progress. They will be
introduced in further patches.

The driver is build tested by Intel's kernel test robot with both GCC and Clang
with several architecture. Sparse reports no warnings.

There are multiple authors, they are listed in alphabetical order below.
