1Common IEEE 802.11 properties 2 3This provides documentation of common properties that are valid for all wireless 4devices. 5 6Optional properties: 7 - ieee80211-freq-limit : list of supported frequency ranges in KHz. This can be 8 used for devices that in a given config support less channels than 9 normally. It may happen chipset supports a wide wireless band but it is 10 limited to some part of it due to used antennas or power amplifier. 11 An example case for this can be tri-band wireless router with two 12 identical chipsets used for two different 5 GHz subbands. Using them 13 incorrectly could not work or decrease performance noticeably. 14 15Example: 16 17pcie@0,0 { 18 reg = <0x0000 0 0 0 0>; 19 wifi@0,0 { 20 reg = <0x0000 0 0 0 0>; 21 ieee80211-freq-limit = <2402000 2482000>, 22 <5170000 5250000>; 23 }; 24}; 25
