> Patch1 - 2: 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 (9):
> drivers core: Add support for Wifi band RF mitigations
> driver core: add ACPI based WBRF mechanism introduced by AMD
> cfg80211: expose nl80211_chan_width_to_mhz for wide sharing
> wifi: mac80211: Add support for ACPI WBRF
> 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 SMU13.0.0
> drm/amd/pm: enable Wifi RFI mitigation feature support for SMU13.0.7
