+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>;
+ };
+ };

The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/vf610-clock.h
for the full list of VF610 clock IDs.
