[PATCH v16 0/9] Enable Wifi RFI interference mitigation feature support

[Ma Jun]

Due to electrical and mechanical constraints in certain platform designs there
may be likely interference of relatively high-powered harmonics of the (G-)DDR
memory clocks with local radio module frequency bands used by Wifi 6/6e/7. To
mitigate possible RFI interference we introuduced WBRF(Wifi Band RFI mitigation Feature).
Producers can advertise the frequencies in use and consumers can use this information
to avoid using these frequencies for sensitive features.

The whole patch set is based on Linux 6.7.0-rc4 With some brief introductions
as below:
Patch1:      Document about WBRF
Patch2:      Core functionality setup for WBRF feature support
Patch3 - 4:  Bring WBRF support to wifi subsystem.
Patch5 - 9:  Bring WBRF support to AMD graphics driver.
