Documentation: mfd: s2mps11: Describe S5M8767 and S2MPS14 clocks

- interrupts: Interrupt specifiers for interrupt sources.

Optional nodes:

- clocks: s2mps11 provides three(AP/CP/BT) buffered 32.768 KHz outputs, so to

  register these as clocks with common clock framework instantiate a sub-node

  named "clocks". It uses the common clock binding documented in :

- clocks: s2mps11 and s5m8767 provide three(AP/CP/BT) buffered 32.768 KHz

  outputs, so to register these as clocks with common clock framework

  instantiate a sub-node named "clocks". It uses the common clock binding

  documented in :

  [Documentation/devicetree/bindings/clock/clock-bindings.txt]

  The s2mps14 provides two (AP/BT) buffered 32.768 KHz outputs.

  - #clock-cells: should be 1.

  - The following is the list of clocks generated by the controller. Each clock

    is assigned an identifier and client nodes use this identifier to specify

    the clock which they consume.

    Clock               ID

    ----------------------

    32KhzAP		0

    32KhzCP		1

    32KhzBT		2

    Clock               ID           Devices

    ----------------------------------------------------------

    32KhzAP		0            S2MPS11, S2MPS14, S5M8767

    32KhzCP		1            S2MPS11, S5M8767

    32KhzBT		2            S2MPS11, S2MPS14, S5M8767

  - compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps14-clk",

		"samsung,s5m8767-clk"

- regulators: The regulators of s2mps11 that have to be instantiated should be

included in a sub-node named 'regulators'. Regulator nodes included in this

		reg = <0x66>;

		s2m_osc: clocks {

			compatible = "samsung,s2mps11-clk";

			#clock-cells = 1;

			clock-output-names = "xx", "yy", "zz";
