Just one bikeshed, otherwise

What about drivers/base/regmap? I haven't looked to closely yet and never
used it in code, but there's a presentation [1] and it sounds like it
provides some nice (and more important standardized) helper stuff for
debug, tracing, ...
Since encoder slave drivers tend to be utterly boring register bashing and
we expect tons of time, I think high levels of standardization would be
really useful. Care to look into this a bit?
Cheers, Daniel
