[PATCH] dt-bindings: iio: st,stm32-adc: add top-level constraints

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Properties with variable number of items per each device are expected to
have widest constraints in top-level "properties:" block and further
customized (narrowed) in "if:then:".  Add missing top-level constraints
for clock-names.
