regmap

I need to inquire about the variability of regmaps across different models. Specifically, I've noticed that the xsTech router machine I currently have utilizes memory locations that differ from the standard model.Could you please confirm whether regmaps indeed vary between models? Any insights or clarification on this matter would be greatly appreciated.

I think Tormach has some interface hardware the uses a microcontroller
implementation of hostmot2. This may well have a different register
map, or at least different addresses. Different register addresses would not
require a driver change.
