1Binding for TI fixed factor rate clock sources.
2
3Binding status: Unstable - ABI compatibility may be broken in the future
4
5This binding uses the common clock binding[1], and also uses the autoidle
6support from TI autoidle clock [2].

11Required properties:
12- compatible : shall be "ti,fixed-factor-clock".
13- #clock-cells : from common clock binding; shall be set to 0.
14- ti,clock-div: fixed divider.
15- ti,clock-mult: fixed multiplier.
16- clocks: parent clock.
17
18Optional properties:
19- ti,autoidle-shift: bit shift of the autoidle enable bit for the clock,
20 see [2]
21- reg: offset for the autoidle register of this clock, see [2]
22- ti,invert-autoidle-bit: autoidle is enabled by setting the bit to 0, see [2]
23- ti,set-rate-parent: clk_set_rate is propagated to parent
24
25Example:
26 clock {
27 compatible = "ti,fixed-factor-clock";
28 clocks = <&parentclk>;
29 #clock-cells = <0>;
30 ti,clock-div = <2>;
31 ti,clock-mult = <1>;
32 };

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