As it turns out, I don't have the time to look into this. The driver is
not exactly big, it is functional, and I would hate if someone else
would duplicate the work just because my driver is not upstream.

So, Greg, can we just get the driver in the kernel tree as is, and if
anyone really cares about it using regmap, that person will convert the
driver later?
