1Binding for TI composite clock.2 3This binding uses the common clock binding[1]. It assumes a4register-mapped composite clock with multiple different sub-types;5 6a multiplexer clock with multiple input clock signals or parents, one7of 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 output12clock, this behaves exactly as [4]13 14The binding must provide a list of the component clocks that shall be15merged to this clock. The component clocks shall be of one of the16"ti,*composite*-clock" types.17 18[1] Documentation/devicetree/bindings/clock/clock-bindings.txt19[2] Documentation/devicetree/bindings/clock/ti/mux.txt20[3] Documentation/devicetree/bindings/clock/ti/divider.txt21[4] Documentation/devicetree/bindings/clock/ti/gate.txt22 23Required properties:24- compatible : shall be: "ti,composite-clock"25- clocks : link phandles of component clocks26- #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
