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

26 - compatible : shall be: "ti,composite-clock"
27 - clocks : link phandles of component clocks
28 - #clock-cells : from common clock binding; shall be set to 0.
31 - clock-output-names : from common clock binding.
