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

9 Required 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
16 Optional 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
24 Example:
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 };

33 dpll_usb_clkdcoldo_ck: dpll_usb_clkdcoldo_ck {
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;
