The below extended map may help and could also be used to help
understand the corner case of VHT80 support on VHT80 center of freq
5690 MHz.

IEEE VHT80 center of freqs possible:

Center                  20 MHz channels                    ath10k capable
        __________  __________  __________  __________
       /          \/          \/          \/          \
5210     5180 (36)   5200 (40)   5220 (44)   5240 (48)           OK
5290     5260 (52)   5280 (56)   5300 (60)   5320 (64)           OK
5530     5500 (100)  5520 (104)  5540 (108)  5560 (112)          OK
5610     5580 (116)  5600 (120)  5620 (124)  5640 (128)          OK
5690     5660 (132)  5680 (136)  5700 (140)  5720 (144)*        Nope
5775     5745 (149)  5765 (153)  5785 (157)  5805 (161)          OK

Other vendor should consider reviewing their own implementation /
support / regulatory considerations / preferences for collateral of
not having a 20 MHz IEEE channel at center of freq 5720 (144) before.
I'll be pushing out how we address this next.
