+Clock bindings for the Cortina Systems Gemini SoC Clock Controller
+
+Required properties :
+- compatible : shall contain the following:
+ "cortina,gemini-clock-controller"
+- #clock-cells should be <1>
+
+The Gemini clock controller needs to be placed as a subnode of the
+system controller.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/cortina,gemini-clock.h header and can be used in device
+tree sources.
+
+Example:
+
+syscon: syscon@40000000 {
+ compatible = "cortina,gemini-syscon", "syscon", "simple-mfd";
+ reg = <0x40000000 0x1000>;
+
+ clock-controller {
+ compatible = "cortina,gemini-clock-controller";
+ #clock-cells = <1>;
+ };
+};
