1Binding for TI fixed factor rate clock sources.
2
3This binding uses the common clock binding[1], and also uses the autoidle
4support from TI autoidle clock [2].

9Required properties:
10- compatible : shall be "ti,fixed-factor-clock".
11- #clock-cells : from common clock binding; shall be set to 0.
12- ti,clock-div: fixed divider.
13- ti,clock-mult: fixed multiplier.
14- clocks: parent clock.
15
16Optional properties:
17- clock-output-names : from common clock binding.
18- ti,autoidle-shift: bit shift of the autoidle enable bit for the clock,
19 see [2]
20- reg: offset for the autoidle register of this clock, see [2]
21- ti,invert-autoidle-bit: autoidle is enabled by setting the bit to 0, see [2]
22- ti,set-rate-parent: clk_set_rate is propagated to parent
23
24Example:
25 clock {
26 compatible = "ti,fixed-factor-clock";
27 clocks = <&parentclk>;
28 #clock-cells = <0>;
29 ti,clock-div = <2>;
30 ti,clock-mult = <1>;
31 };

34 #clock-cells = <0>;
35 compatible = "ti,fixed-factor-clock";
36 clocks = <&dpll_usb_ck>;
37 ti,clock-div = <1>;
38 ti,autoidle-shift = <8>;
39 reg = <0x01b4>;
40 ti,clock-mult = <1>;
41 ti,invert-autoidle-bit;
