After applying this to my local tree, as it is a dependency for 2/4 in
for-mfd-next:

Documentation/devicetree/bindings/display/xylon,logicvc-display.yaml:
properties:clock-names: {'required': ['maxItems']} is not allowed for
{'minItems': 1, 'maxItems': 4, 'items': [{'const': 'vclk'}, {'enum':
['vclk2', 'lvdsclk', 'lvdsclkn']}, {'enum': ['vclk2', 'lvdsclk',
'lvdsclkn']}, {'enum': ['vclk2', 'lvdsclk', 'lvdsclkn']}]}
hint: "maxItems" is not needed with an "items" list
from schema $id: http://devicetree.org/meta-schemas/items.yaml#

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
