Are you pointing me in this direction ? ;-) I was more thinking about whether it would be useful to use for this MFD hub. So that for this MFD and it's children, you would use regmap to: 1) Cache registers 2) Marshall the register read/writes across USB I don't think it would be applicable for USB, as reading & writing registers across USB is a pretty odd usecase.

I was mainly thinking about the Viperboard MFD complex. > I would stay at the "cache" implementation I presented in the patch - this is > too special. You're special just like everybody else ;-) But to be honest I haven't seen another USB device like this. Which probably means that next week there will be dozens of them...
