+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.
