+Binding for Samsung S2MPS11 32k clock generator block
+
+This is a part of device tree bindings of S2MPS11 multi-function device.
+More information can be found in bindings/mfd/s2mps11.txt file.
+
+The S2MPS11 contains three 32.768khz clock outputs that can be controlled
+(gated/ungated) over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Required properties:
+- #clock-cells: From common clock binding; shall be set to 1.
+
+Optional properties:
+- clock-output-names: From common clock binding.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. Following indices are allowed:
+     - 0: 32khz_ap clock,
+     - 1: 32khz_cp clock.
+     - 2: 32khz_bt clock
+
+Clocks are defined as preprocessor macros in dt-bindings/clock/samsung,s2mps11.h
+header and can be used in device tree sources.
+
+Example: Node of the MFD chip
+
+	s2mps11: s2mps11@66 {
+		compatible = "samsung,s2mps11";
+		interrupt-parent = <&wakeup_eint>;
+		interrupts = <26 0>;
+		reg = <0x66>;
+		#clock-cells = <1>;
+
+		/* ... */
+	};
+
+Example: Clock consumer node
+
+	foo@0 {
+		compatible = "bar,foo";
+		/* ... */
+		clock-names = "my-clock";
+		clocks = <&s2mps11 S2MPS11_CLK_32K_AP>;
+	};
+
+Presently (19.3.2015) the above said is not correct yet.
+Until s2mps11 mfd driver is updated you still need to specify like that:
+
+	s2mps11: s2mps11@66 {
+		compatible = "samsung,s2mps11-pmic";
+		reg = <0x66>;
+		s2mps11_osc: clocks {
+			#clock-cells = <1>;
+			clock-output-names = "s2mps11_ap",
+				"s2mps11_cp", "s2mps11_bt";
+                        };
+		/* ... */
+	}
+
+	foo@0 {
+		compatible = "bar,foo";
+		/* ... */
+		clock-names = "my-clock";
+	        clocks = <&s2mps11_osc S2MPS11_CLK_AP>;
+
+};
