[v7,00/12] wifi: ath11k: add support for 6 GHz station for various modes : LPI, SP and VLP

Message

This introduced some new concept:
power type of AP(STANDARD_POWER_AP, INDOOR_AP, VERY_LOW_POWER_AP)
power type of STATION(DEFAULT_CLIENT, SUBORDINATE_CLIENT)
power spectral density(psd)

This patchset is to implement the new rules for 6 GHz band in
ath11k.

ath11k parsed the reg rules from new WMI event
WMI_REG_CHAN_LIST_CC_EXT_EVENTID and parse the
transmit power envelope element in beacon of AP
and then set new WMI command WMI_VDEV_SET_TPC_POWER_CMDID
to firmware when connect to 6G AP, also support backward
compatibility with firmware which not support new wmi
cmd WMI_VDEV_SET_TPC_POWER_CMDID.

v7: address review comments per Kalle, Jeff and Aditya. Also rebased to ToT.

v6: (NOT depends to any patch now)
   1. The dependent patch "wifi: cfg80211: save power spectral density(psd) of regulatory rule"
      has upstream to wireless-next https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next.git/commit/?id=ddd7f45c899f7524bdbe6a32fe4906cde8b07b9b
      The prerequisite-patch is cherry-pick from wireless-next
      So add back the other patches in v3 since no dependency to cfg80211 public patch above now.

v4: (NOT depends to any patch now).
   1. removed patches which depends on
      wifi: cfg80211: save Power Spectral Density (PSD) of the regulatory rule
      https://lore.kernel.org/linux-wireless/[e-mail]/
      removed:
      [v3,08/15] wifi: ath11k: save power spectral density(psd) of regulatory rule

v3:
   1. added "ath11k: fix a possible dead lock caused by ab->base_lock".
   3. deleted "ath11k: add support for extended wmi service bit" which is alreay upstream.

v2:
   1. change some minor comments by Kalle.
