| Binding for TI composite clock. | |
| Binding status: Unstable - ABI compatibility may be broken in the future | |
| This binding uses the common clock binding[1]. It assumes a | |
| register-mapped composite clock with multiple different sub-types; | |
| a multiplexer clock with multiple input clock signals or parents, one | |
| of which can be selected as output, this behaves exactly as [2] | |
| an adjustable clock rate divider, this behaves exactly as [3] | |
| a gating function which can be used to enable and disable the output | |
| clock, this behaves exactly as [4] | |
| The binding must provide a list of the component clocks that shall be | |
| merged to this clock. The component clocks shall be of one of the | |
| "ti,*composite*-clock" types. | |

| Required properties: | |
| - compatible : shall be: "ti,composite-clock" | |
| - clocks : link phandles of component clocks | |
| - #clock-cells : from common clock binding; shall be set to 0. | |
| Examples: | |
| usb_l4_gate_ick: usb_l4_gate_ick { | |
| #clock-cells = <0>; | |
| compatible = "ti,composite-interface-clock"; | |
| clocks = <&l4_ick>; | |
| ti,bit-shift = <5>; | |
| reg = <0x0a10>; | |
| }; | |
| usb_l4_div_ick: usb_l4_div_ick { | |
| #clock-cells = <0>; | |
| compatible = "ti,composite-divider-clock"; | |
| clocks = <&l4_ick>; | |
| ti,bit-shift = <4>; | |
| ti,max-div = <1>; | |
| reg = <0x0a40>; | |
| ti,index-starts-at-one; | |
| }; | |
| usb_l4_ick: usb_l4_ick { | |
| #clock-cells = <0>; | |
| compatible = "ti,composite-clock"; | |
| clocks = <&usb_l4_gate_ick>, <&usb_l4_div_ick>; | |
