Did you actually test putting this many interrupts into a node? AFAICT, any more than 6 will cause complaints. Thanks, Conor.

I misunderstood Rob's comment. Now I'm not sure whether dt-binding can support regex or something or not, or let ask for advice in the following way: how could I write the dt-binding in this case? I didn't find similar examples so far. I'm not sure listing possible description and const properties for all channel interrupts is suitable. > Did you actually test putting this many interrupts into a node? > AFAICT, any more than 6 will cause complaints. I tried 12rx and 12tx interrupts in a node, didn't see dtc warning. so I guess the complaints are from dtb check? I will try to reproduce them. > > Thanks, > Conor.

I reproduced the complaints and fixed them by adding additionalItems and maxItems. PS: those per-channel and safety irqs are optional.
