Kalle Valo says:

====================
wireless-drivers-next patches for 5.4

Last set of patches for 5.4. wil6210 and rtw88 being most active this
time, but ath9k also having a new module to load devices without
EEPROM.

Major changes:

wil6210

* add support for Enhanced Directional Multi-Gigabit (EDMG) channels 9-11

* add debugfs file to show PCM ring content

* report boottime_ns in scan results

ath9k

* add a separate loader for AR92XX (and older) pci(e) without eeprom

brcmfmac

* use the same wiphy after PCIe reset to not confuse the user space

rtw88

* enable interrupt migration

* enable AMSDU in AMPDU aggregation

* report RX power for each antenna

* enable to DPK and IQK calibration methods to improve performance
====================
