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.

Evan Quan (6):
  cfg80211: expose nl80211_chan_width_to_mhz for wide sharing
  wifi: mac80211: Add support for WBRF features
  drm/amd/pm: update driver_if and ppsmc headers for coming wbrf feature
  drm/amd/pm: setup the framework to support Wifi RFI mitigation feature
  drm/amd/pm: add flood detection for wbrf events
  drm/amd/pm: enable Wifi RFI mitigation feature support for SMU13.0.7

Ma Jun (3):
  Documentation/driver-api: Add document about WBRF mechanism
  platform/x86/amd: Add support for AMD ACPI based Wifi band RFI
    mitigation feature
  drm/amd/pm: enable Wifi RFI mitigation feature support for SMU13.0.0

Hi all,

Compared with the previous version(v15), only patch 1 was modified to fix compilation errors,
and other patches remained the same as the previous version.

Regards,
Ma Jun
