Joakim Zhang July 21, 2021, 10:12 a.m. UTC 
This patch improves the yaml a bit according to Rob Herring comments:
1) normalize interrupt-names property, there is no reason to support
random order.
2) validate each string in clock-names property.
3) add constraints for fsl,num-tx-queues/fsl,num-rx-queues property.
4) change additionalProperties to false in order to do strict checking.
