To: ath12k; +Cc: linux-wireless, Aishwarya R
There are 3 types of regulatory rules for AP mode and 6 types for
STATION mode. This is to add wmi_vdev_type and ieee80211_ap_reg_power
to select the exact reg rules.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

Wen,
Can you provide a "Tested-on: WCN7850" tag for this series?

where is power_type coming from and can it be tainted?
if we always expect a valid value then why not just have the conversion
function set the default to WMI_REG_INDOOR_AP?
Are there places in upcoming patches that actually perform error
handling if the conversion function returns MAX?

please avoid splitting lines in the middle of a variable reference; that
decreases the readability of the code. It is better to exceed some
arbitrary line length guideline. you can use a client_type =
WMI_REG_DEFAULT_CLIENT assignment to help reduce the length.
if the line is still exceedingly long, split the lines after =
repeat for all cases that follow

avoid splitting the line between a function and it's parameters.
it is ok to split in the middle of a parameter list, but the first
parameter should almost always be on the same line as the function

Jeff, it is this tag below.
I have not tested this serials on WCN7850.
Should I test this serials on WCN7850?
Tested-on: WCN7850 hw2.0 PCI
WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4

During bootup, WMI_REG_CHAN_LIST_CC_EXT_EVENTID event sent from firmware
at an early stage and it expects the 6 GHz power type for 6 GHz reg rules.
As power mode is not defined at this point host selects IEEE80211_REG_UNSET_AP
as default mode.
When interface is created, it updates regd rules accordingly.

Again what is "it"?
I'm having trouble discerning what is existing behavior and what is new
behavior.
That distinction should be clear. In the past the following template
has been suggested:
" Current code does (A), this has a problem when (B).
We can improve this doing (C), because (D)."
<http://www.spinics.net/lists/kernel/msg1633438.html>
Obviously that exact format isn't required, but you should at least
describe, if it isn't obvious:
1) what does the current code do
2) what is wrong with that code
3) what should be done to the code to fix the issue
I don't actually have an code patch comments

When 6 GHz AP or STA is assigned a channel ctx, it needs to
extract the power type from HE operation element.
If unset power type is present, by default IEEE80211_REG_LPI_AP
power mode will be used.

Save the Power Spectral Density(PSD) report from firmware
to struct ieee80211_reg_rule. 6 GHz regulatory domains
introduces PSD. The PSD value of the regulatory rule should
be taken into effect for the ieee80211_channels falling into
that particular regulatory rule.

should parse it according to IEEE Std 802.11ax™‐2021.

When STATION is connected to a 6 GHz AP, or when AP boots up, it has
2 ways to configure the power limit to firmware. Currently it
sends 2 wmi command WMI_PDEV_PARAM_TXPOWER_LIMIT2G/
WMI_PDEV_PARAM_TXPOWER_LIMIT5G to firmware.
Add support to send WMI_VDEV_SET_TPC_POWER_CMDID to firmware which
include more parameters for power control. When firmware support
SERVICE_EXT_TPC_REG, it means firmware support this feature, then ath12k
discard BSS_CHANGED_TXPOWER flag from mac80211 which is used to the first
way for 6 GHz band.
The second way is to prepare the parameter for wmi command
WMI_VDEV_SET_TPC_POWER_CMDID and send the firmware after vdev start
response success from firmware.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

I'm not parsing this last sentence. s I mentioned in a previous patch,
it will be easier to understand if you break it down:
what the current code does
what is wrong with the current code
how to fix the current code

this complex test occurs in two places. can it be refactored into a
