[PATCH 3/5] dt-bindings: gpu: samsung: constrain clocks in top-level properties

[Krzysztof Kozlowski]

When number of clock varies between variants, the Devicetree bindings
coding convention expects to have widest constraints in top-level
definition of the properties and narrow them in allOf:if:then block.

This is more readable and sometimes allows to spot some errors in the
bindings.
