Well, I wasn't aware enums were supposed to be sorted. That doesn't seem to be
documented anywhere. In fact, in example-schema.yaml the enum is not sorted [1].
So it'd be great to update that example to follow that rule as well as
explicitly document it. Maybe even a dt-binding check that checks for this?
That'll make it much easier to learn about and follow this rule :).

I don't think it'd be worth it to send another patch just to fix sorting in
this case as it's already been merged, but I'll keep this in mind whenever I
send future dt-binding patches.

Thanks,
Nícolas
