- some ship with a broken EEPROM that enables the 5GHz band on a
2.4GHz-only card, which is why we need "qca,disable-5ghz"

No. You just need to use ieee80211-freq-limit.

you are right with this one, "qca,disable-5ghz" is an out-of-tree
patch and ieee80211-freq-limit support should be added upstream
instead
however, the cause is still the same (devices are shipped with an
EEPROM which has the 5GHz band enabled while it shouldn't have)
