clk: ti: Add support for dm814x ADPLL

Binding for Texas Instruments ADPLL clock.

Binding status: Unstable - ABI compatibility may be broken in the future

This binding uses the common clock binding[1]. It assumes a

register-mapped ADPLL with two to three selectable input clocks

and three to four children.

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

Required properties:

- compatible : shall be one of "ti,dm814-adpll-s-clock" or

  "ti,dm814-adpll-lj-clock" depending on the type of the ADPLL

- #clock-cells : from common clock binding; shall be set to 1.

- clocks : link phandles of parent clocks clkinp and clkinpulow, note

  that the adpll-s-clock also has an optional clkinphif

- reg : address and length of the register set for controlling the ADPLL.

Examples:

	adpll_mpu_ck: adpll@40 {

		#clock-cells = <1>;

		compatible = "ti,dm814-adpll-s-clock";

		reg = <0x40 0x40>;

		clocks = <&devosc_ck &devosc_ck &devosc_ck>;

		clock-names = "clkinp", "clkinpulow", "clkinphif";

		clock-output-names = "481c5040.adpll.dcoclkldo",

				     "481c5040.adpll.clkout",

				     "481c5040.adpll.clkoutx2",

				     "481c5040.adpll.clkouthif";

	};

	adpll_dsp_ck: adpll@80 {

		#clock-cells = <1>;

		compatible = "ti,dm814-adpll-lj-clock";

		reg = <0x80 0x30>;

		clocks = <&devosc_ck &devosc_ck>;

		clock-names = "clkinp", "clkinpulow";

		clock-output-names = "481c5080.adpll.dcoclkldo",

				     "481c5080.adpll.clkout",

				     "481c5080.adpll.clkoutldo";

	};
