29 description: The Si3474 is a single-chip PoE PSE controller managing
30 8 physical power delivery channels. Internally, it's structured
31 into two logical "Quads".
32 Quad 0 Manages physical channels ('ports' in datasheet) 0, 1, 2, 3
33 Quad 1 Manages physical channels ('ports' in datasheet) 4, 5, 6, 7.
