I raised the issue with Marvell early on, but didn't get too far.

Interesting. I'd made a real effort to get the hard delays out of there, though. Might the real solution be to use hrtimers here? There's a *lot* of registers to write, I hate to hog the CPU for 2ms for every single one of them. That said, the hard delays are clearly better than what was there before. jon
