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.

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.
