I don't have any more protection than any other driver that accesses SOC
registers directly. Last I heard, Zhang's DMA driver was in limbo, and that
driver would be the best place to arbitrate DMA register access. I was planning
on adding arbitration support to that driver after both drivers were applied.
As for the GUTS driver, well, I just program a few registers at startup, and I
don't think any other driver touches them.
