Compatible strings should not include a 'x' wildcard like this, better use
the specific chip name.

Also, it sounds like you named them after the board vendor, which sounds
wrong as the vendor part of the compatible string should be the whoever
made that part (analog?)

interrupt-parent should be an optional property, or you can leave it out,
as this is a standard property that can always be there when there is
interrupts.
