This can be used for devices that in a given config support less channels than normally. It may happen chipset supports a wide wireless band but it is limited to some part of it due to used antennas or power amplifier. An example case for this can be tri-band wireless router with two identical chipsets used for two different 5 GHz subbands. Using them incorrectly could not work or decrease performance noticeably additionalProperties: true examples: - | pcie0 { #address-cells = <3>; #size-cells = <2>; wifi@0,0 { reg = <0x0000 0 0 0 0>; ieee80211-freq-limit = <2402000 2482000>, <5170000 5250000>; }; };
