1Binding for TI composite clock. 2 3This binding uses the common clock binding[1]. It assumes a 4register-mapped composite clock with multiple different sub-types; 5 6a multiplexer clock with multiple input clock signals or parents, one 7of which can be selected as output, this behaves exactly as [2] 8 9an adjustable clock rate divider, this behaves exactly as [3] 10 11a gating function which can be used to enable and disable the output 12clock, this behaves exactly as [4] 13 14The binding must provide a list of the component clocks that shall be 15merged to this clock. The component clocks shall be of one of the 16"ti,*composite*-clock" types. 17 18[1] Documentation/devicetree/bindings/clock/clock-bindings.txt 19[2] Documentation/devicetree/bindings/clock/ti/mux.txt 20[3] Documentation/devicetree/bindings/clock/ti/divider.txt 21[4] Documentation/devicetree/bindings/clock/ti/gate.txt 22 23Required properties: 24- compatible : shall be: "ti,composite-clock" 25- clocks : link phandles of component clocks 26- #clock-cells : from common clock binding; shall be set to 0. 27 28Optional properties: 29- clock-output-names : from common clock binding. 30 31Examples: 32 33usb_l4_gate_ick: usb_l4_gate_ick { 34 #clock-cells = <0>; 35 compatible = "ti,composite-interface-clock"; 36 clocks = <&l4_ick>; 37 ti,bit-shift = <5>; 38 reg = <0x0a10>; 39}; 40 41usb_l4_div_ick: usb_l4_div_ick { 42 #clock-cells = <0>; 43 compatible = "ti,composite-divider-clock"; 44 clocks = <&l4_ick>; 45 ti,bit-shift = <4>; 46 ti,max-div = <1>; 47 reg = <0x0a40>; 48 ti,index-starts-at-one; 49}; 50 51usb_l4_ick: usb_l4_ick { 52 #clock-cells = <0>; 53 compatible = "ti,composite-clock"; 54 clocks = <&usb_l4_gate_ick>, <&usb_l4_div_ick>; 55}; 56
