| 2 | |
| 3 | This provides documentation of common properties that are valid for all wireless |
| 4 | devices. |
| 5 | |
| 6 | Optional 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. |

| 15 | Example: |
| 16 | |
| 17 | pcie@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 | }; |
