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

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.
