+* Clock bindings for the Cirrus Logic CLPS711X CPUs
+
+Required properties:
+- compatible : Shall contain "cirrus,clps711x-clk".
+- reg : Address of the internal register set.
+- startup-frequency: Factory set CPU startup frequency in HZ.
+- #clock-cells : Should be <1>.
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/clps711x-clock.h
+for the full list of CLPS711X clock IDs.
+
+Example:
+ clks: clks@80000000 {
+ #clock-cells = <1>;
+ compatible = "cirrus,ep7312-clk", "cirrus,clps711x-clk";
+ reg = <0x80000000 0xc000>;
+ startup-frequency = <73728000>;
+ };
