So it is a v6 and it is the first version you send to proper maintainers
using get_maintainers.pl... sigh...

This is wrong. You said in interrupts you can have two items, but here
you list only one. I don't know what do you want to achieve here.

Why this is so flexible? Any device allows any interrupt to be present
or not?

This is not a list. Just enums, no items.

Aren't you using interrupt flags? If so, use defines.

I only noticed the missing cc on v5 - wasn't paying attention to the binding
as lots of stuff in the driver...

However, how did this pick up an rtc binding for a totally different part?

Aim is 0, 1 or 2 interrupts + knowing which ones they are.
Device has two pins that have very similar functionality and board
designers are likely to pick one or the two more or less at random depending
on which trace is easier to route.

So my guess is this needs minItems, maxItems.

The current choice allows 0 or 1 interrupt. If you want 0-2 then it
should be:

minItems: 1
items:
  - enum: [gpio0, gpio1]
  - const: gpio1

This one would also work:

minItems: 1
maxItems: 2
items:
  enum: [gpio0, gpio1]

but the order of interrupts should be rather defined, so I would prefer
first.


Best regards,
Krzysztof
