ath9k: OF: qca,disable-(2|5)ghz => ieee80211-freq-limit
OpenWrt maintains two special out-of-tree DT properties: "qca,disable-5ghz" and "qca,disable-2ghz". These are implemented in a mac80211 ath9k patch "550-ath9k-disable-bands-via-dt.patch". With the things being what they are, now might be a good point to switch the devices to the generic and upstream "ieee80211-freq-limit" property. This property is much broader and works differently. Instead of disabling the drivers logic which would add the affected band and channels. It now disables all channels which are not within the specified frequency range.

+Subject: ath9k: support DT ieee80211-freq-limit property to limit channels
+
+The common DT property can be used to limit the available channels
+but ath9k has to manually call wiphy_read_of_freq_limits().
+
+I would have put this into ath9k_of_init(). But it didn't work there.
+The reason is that in ath9k_of_init() the channels and bands are not yet
+registered in the wiphy struct. So there isn't any channel to flag as
+disabled.
