Hmm. I see your point now.

dma-names:
description:
There must be at least one channel named "tx" for transmit and named "rx"
for receive.
minItems: 2
maxItems: 32
additionalItems: true
items:
- const: rx
- const: tx


I was expecting above to allow adding the items in any order, but
looks like the order is fixed with this.
