+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Currently various "fixed" clocks are declared for peripheral drivers that use
+the common clock framework to reference their core clocks. Proper support of
+these clocks will be added later
+
+Device tree example:
+
+       clocks {
+               #address-cells = <1>;
+               #size-cells = <1>;
+               ranges;
+
+               osc: oscillator {
+                       compatible = "fixed-clock";
+                       #clock-cells = <1>;
+                       clock-frequency = <25000000>;
+               };
+
+               apb_clk: apb_clk {
+                       compatible = "fixed-clock";
+                       #clock-cells = <0>;
+                       clock-frequency = <1000000000>;
+               };
+
+               periph_clk: periph_clk {
+                       compatible = "fixed-clock";
+                       #clock-cells = <0>;
+                       clock-frequency = <500000000>;
+               };
+       };
