+Binding for Samsung S2M and S5M family clock generator block
+============================================================
+
+This is a part of device tree bindings for S2M and S5M family multi-function
+devices.
+More information can be found in bindings/mfd/sec-core.txt file.
+
+The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
+outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
+
+To register these as clocks with common clock framework instantiate under
+main device node a sub-node named "clocks".
+
+It uses the common clock binding documented in:
+ - Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+
+Required properties of the "clocks" sub-node:
+ - #clock-cells: should be 1.
+ - compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
+ "samsung,s2mps14-clk", "samsung,s5m8767-clk"
+ The S2MPS15 uses the same compatible as S2MPS13, as both provides similar
+ clocks.
+
+
+Each clock is assigned an identifier and client nodes use this identifier
+to specify the clock which they consume.

+Include dt-bindings/clock/samsung,s2mps11.h file to use preprocessor defines

+ compatible = "samsung,s2mps11-pmic";
+ reg = <0x66>;

+ s2m_osc: clocks {
+ compatible = "samsung,s2mps11-clk";
+ #clock-cells = <1>;
+ clock-output-names = "xx", "yy", "zz";
+ };
