Sorry. Misunderstood the question. Yes, I ran make dtbs_check and
got these messages. But couldn't relate them with the
minItems/maxItems mismatch...

	phy at 7d000: clocks: [[8, 93], [8, 102]] is too short
	phy at 7d000: clock-names: ['aux', 'cfg_ahb'] is too short

Will fix it now. Thanks for the clarification.
