   4 Subject: [PATCH] ath10k: Limit available channels via DT ieee80211-freq-limit
   5
   6 Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
   7 the RX and TX path. These filtered channel can in theory still be used by
   8 the hardware but the signal strength is reduced so much that it makes no
   9 sense.
  10
  11 There is already a DT property to limit the available channels but ath10k
  12 has to manually call this functionality to limit the currrently set wiphy
  13 channels further.
