+Subject: [PATCH] ath10k: Limit available channels via DT ieee80211-freq-limit
+
+Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
+the RX and TX path. These filtered channel can in theory still be used by
+the hardware but the signal strength is reduced so much that it makes no
+sense.
+
+There is already a DT property to limit the available channels but ath10k
+has to manually call this functionality to limit the currrently set wiphy
+channels further.
