V2: Switch to a single ieee80211-freq-limit property that allows specifying
*multiple* ranges. This resolves problem with more complex rules as pointed
by Felx.
Make description implementation agnostic as pointed by Arend.
Rename node to wifi as suggested by Martin.
V3: Use more real-life frequencies in the example.
V5: Describe hardware design as possible use for this property

+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 to specify extra hardware limitations caused by e.g. used antennas
+ or power amplifiers.
+
+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>;
+ };
+};
