Coming back to the discussion on driver model....
How do you specify the fields? I would expect that this would be done in the driver tree? Perhaps in a subnode of the device?
Just to state what I see as the advantages of using a separate device for access:
- Remove the #ifdef in the regmap struct - Easy to specify the behaviour in a device-tree node - Easy to extend as the child device can do what it likes with respect to access
Disadvantage is that it takes a bit more space.
