51 * it has to store a reference back to its _core equivalent structure,
52 * so that it can service the hardware by steering gpio's etc.
53 * Each bridge implementation is different so cast devptr accordingly.
54 * The xc5000 driver cares not for this value, other than ensuring
55 * it's passed back to a bridge during tuner_callback().
