Signed-off-by: Rafał Miłecki --- 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. --- .../devicetree/bindings/net/wireless/ieee80211.txt | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/wireless/ieee80211.txt diff --git a/Documentation/devicetree/bindings/net/wireless/ieee80211.txt b/Documentation/devicetree/bindings/net/wireless/ieee80211.txt new file mode 100644 index 0000000..0cd1219 --- /dev/null +++ b/Documentation/devicetree/bindings/net/wireless/ieee80211.txt @@ -0,0 +1,18 @@ +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 + +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>; + }; +}; -- 2.10.1
