[PATCH 02/15] ath11k: Add support to parse new wmi event for 6 GHz regulatory
Wen Gong

Tue Oct 26 04:19:00 PDT 2021
In order to support different power levels of 6 GHz AP and client, new
wmi event for regulatory was added in firmware(WMI_REG_CHAN_LIST_CC_EXT_EVENTID)
to provide new parameters required for 6 GHz regulatory rules.
firmware advertises its capability of handling new event in wmi service ready
event. Based on that, host needs to set host_service_flags in wmi init
command to indicate that host supports processing of new wmi event.
Based on advertised host capability, firmware decides to send old event
(WMI_REG_CHAN_LIST_CC_EVENTID) or new event(WMI_REG_CHAN_LIST_CC_EXT_EVENTID).
Add support for parsing 2.4 GHz/5 GHz/6 GHz reg rules and other parameters from
WMI_REG_CHAN_LIST_CC_EXT_EVENTID, to populate the channel lists.
Since 6 GHz requires additional power value fields(PSD info), update
reg rule parsing function.
