1 Binding for Texas Instruments ADPLL clock.
2
3 Binding status: Unstable - ABI compatibility may be broken in the future
4
5 This binding uses the common clock binding[1]. It assumes a
6 register-mapped ADPLL with two to three selectable input clocks
7 and three to four children.

11 Required properties:
12 - compatible : shall be one of "ti,dm814-adpll-s-clock" or
13   "ti,dm814-adpll-lj-clock" depending on the type of the ADPLL
14 - #clock-cells : from common clock binding; shall be set to 1.
15 - clocks : link phandles of parent clocks clkinp and clkinpulow, note
16   that the adpll-s-clock also has an optional clkinphif
17 - reg : address and length of the register set for controlling the ADPLL.
