Can you elaborate on what was tested in your commit text? And more
importantly, what is the impact on existing devices, especially given that
existing devices would not have calibration data for this channel in the board
files? Does the QCA988x board file even have calibration data for this channel?

what is the diff from v1?
for future reference when you submit a new version of a patch you should
include a patch changelog after the ---, see:

In the case of ath10k we use an external regulatory database.
For the country "US" channels 169, 173 and 177 are marked as NO-IR and
we cannot run AP on them.
Even if channels are not disabled in the board files:
            * 5845.0 MHz [169] (27.0 dBm) (no IR)
            * 5865.0 MHz [173] (27.0 dBm) (no IR)
            * 5885.0 MHz [177] (27.0 dBm) (no IR)

I only tested the use as a client on channel 177:
root@OpenWrt:~# iwinfo phy1 scan
Cell 01 - Address: XX:XX:XX:XX:XX:XX
          ESSID: "ch177"
          Mode: Master  Frequency: 5.885 GHz  Band: 5 GHz  Channel: 177
          Signal: -43 dBm  Quality: 67/70
          Encryption: mixed WPA2/WPA3 PSK/SAE (CCMP)
          HT Operation:
                    Primary Channel: 177
                    Secondary Channel Offset: no secondary
                    Channel Width: 20 MHz

There are no differences. My previous patch was deferred. I don't know
exactly how to proceed in such a case.

I wonder how this works with QCA6174, unfortunately I'm not able to test
that.

I only tested on QCA988X, QCA9984 and IPQ4019 as clients.
