If you have a list of items (const or description, doesn't matter), you don't have to specify maxItems, as it is implicitly equal to the number of items. Also, specifying minItems means that you're "setting" one or more items as optional. It looks like you're specifying a specific and definite list of items for both clocks and clock-names... and for all of the supported SoCs, so, I don't think that having {min,max}Items globally specified on clocks, clock-names make any kind of sense. .....but I'd like for someone else to give an opinion on this as well.
