- 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.
