Yes, that's not really satisfying.

I will tweak the driver so that it reads as much as possible from
registers. Currently, I'm considering adopting SoC-e IP Core families as
the compatible option. In my case, that would mean soce,mrs. Or if still
too generic something like mrs-switch-v1.0 or mrs-basic.

However, I won't be able to submit a v2 in the next few weeks. Maybe
I (or someone else) will come up with something better by then.
