'make dt_binding_check' will give more detailed errors. Are the inputs always contiguous 0-N? If so, you want: items: - const: clkout0 - const: clkout1 - const: clkout2 ... If you want to express any number and order of strings is valid, then you need: items: enum: - clkout0 - clkout1 - clkout2 Doing that is discouraged for bindings though. Currently, it will generate an error from the meta-schema, but we could change that. Rob
