-Common IEEE 802.11 properties
-
-This provides documentation of common properties that are valid for all wireless
-devices.
-
-Optional properties:
- - ieee80211-freq-limit : list of supported frequency ranges in KHz. 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.
-
-Example:
-
-pcie@0,0 {
-	reg = <0x0000 0 0 0 0>;
-	wifi@0,0 {
-		reg = <0x0000 0 0 0 0>;
-		ieee80211-freq-limit = <2402000 2482000>,
-				       <5170000 5250000>;
-	};
-};
