1 Binding for TI composite clock.
3 This binding uses the common clock binding[1]. It assumes a
4 register-mapped composite clock with multiple different sub-types;
6 a multiplexer clock with multiple input clock signals or parents, one
7 of which can be selected as output, this behaves exactly as [2]
9 an adjustable clock rate divider, this behaves exactly as [3]
11 a gating function which can be used to enable and disable the output
12 clock, this behaves exactly as [4]
14 The binding must provide a list of the component clocks that shall be
15 merged to this clock. The component clocks shall be of one of the
16 "ti,*composite*-clock" types.

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.
29 - clock-output-names : from common clock binding.
