As before, you need 'minItems: 4' in the previous patch.

If you aren't clear what's needed, run 'make dtbs_checks' yourself 
before submitting again.

No, you just threw out the order requirements. And this schema will be 
true with just 1 of the strings below plus any other strings. For 
example, this will pass:

clock-names = "foo", "bar", "axi", "baz", "rob";
