Makes sense, I'll remove this in the next revision.

In the case of new chip, interrupts are not tied for a specific purpose 
unlike the case of IPQ8074/IPQ6018 where the driver searches an IRQ 
based on name. That is the reason why interrupt-names are omitted for 
the new chip.

I'll change it.

You mean something like this shown below?

   iommus:
     minItems: 1
     maxItems: 2

   wifi-firmware:
     type: object
     description: |
       WCN6750 wifi node can contain one optional firmware subnode.
       Firmware subnode is needed when the platform does not have 
Tustzone.
     required:
       - iommus
