This adds device tree bindings and a header for the Gemini SoC
Clock Controller.
Signed-off-by: Linus Walleij <linus.walleij@xxxxxxxxxx>

ChangeLog v1->v2:
- Move the clock controller to be directly in the parent syscon
node.

+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 identical to the system controller
+node.
+
+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", "cortina,gemini-clock-controller",
+ "syscon", "simple-mfd";
+ reg = <0x40000000 0x1000>;
+ #clock-cells = <1>;
+};
