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]. 7 8[1] Documentation/devicetree/bindings/clock/clock-bindings.txt 9[2] Documentation/devicetree/bindings/clock/ti/autoidle.txt 10 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- clock-output-names : from common clock binding. 20- ti,autoidle-shift: bit shift of the autoidle enable bit for the clock, 21 see [2] 22- reg: offset for the autoidle register of this clock, see [2] 23- ti,invert-autoidle-bit: autoidle is enabled by setting the bit to 0, see [2] 24- ti,set-rate-parent: clk_set_rate is propagated to parent 25 26Example: 27 clock { 28 compatible = "ti,fixed-factor-clock"; 29 clocks = <&parentclk>; 30 #clock-cells = <0>; 31 ti,clock-div = <2>; 32 ti,clock-mult = <1>; 33 }; 34 35 dpll_usb_clkdcoldo_ck: dpll_usb_clkdcoldo_ck { 36 #clock-cells = <0>; 37 compatible = "ti,fixed-factor-clock"; 38 clocks = <&dpll_usb_ck>; 39 ti,clock-div = <1>; 40 ti,autoidle-shift = <8>; 41 reg = <0x01b4>; 42 ti,clock-mult = <1>; 43 ti,invert-autoidle-bit; 44 };
