Subject: [PATCH v3 01/15] wifi: ath11k: Add support to parse new wmi event for 6 GHz regulatory
Date:   Tue, 13 Sep 2022 01:15:04 -0400
Message-ID: <20220913051518.23051-2-quic_wgong@quicinc.com>

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.
