Let's add binding documentation for the ADPLL found on dm814x
and dra62x. The binding uses the standard clock binding.

+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 0.
+- 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-indices = <0>, <1>, <2>, <3>;
+ 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-indices = <0>, <1>, <2>;
+ clock-output-names = "481c5080.adpll.dcoclkldo",
+ "481c5080.adpll.clkout",
+ "481c5080.adpll.clkoutldo";
+ };
