I saw the warning, but since I had copied that part of the example from
apple,admac.yaml I didn’t make much of it. Now that I look at it again,
the example in apple,admac doesn’t raise the same warning, how come?

This is just a curiosity since we don’t need the aic node in the example
anyway (unlike in apple,admac where it’s needed because of empty entries
in interrupts-extended).
