+* Device tree binding for CPU boost frequency (aka over-clocking)
+
+Certain CPU's can be operated in optional 'boost' mode (or sometimes referred as
+overclocking) in which the CPU can operate at frequencies which are not
+specified by the manufacturer as CPU's operating frequency.
+
+Optional Properties:
+- boost-frequencies: list of frequencies in KHz to be used only in boost mode.
+ This list should be a subset of frequencies listed in "operating-points"
+ property. Refer to Documentation/devicetree/bindings/power/opp.txt for
+ details about "operating-points" property.
+
+Example:
+
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cpu@0 {
+ device_type = "cpu";
+ compatible = "arm,cortex-a9";
+ reg = <0>;
+
+ operating-points = <
+ 1500000 1350000
+ 1400000 1287500
+ 1300000 1250000
+ 1200000 1187500
+ 1100000 1137500
+ 1000000 1087500
+ >;
+ boost-frequencies = <1500000 1400000>;
+ };
+ cpu@1 {
+ device_type = "cpu";
+ compatible = "arm,cortex-a9";
+ reg = <1>;
+ };
+ };
