Ok I agree, in this particular an simple API will do the job fine but I
still wanted to know if it is possible to register a "soft device" (more
complicated than my simple MRAM register) to link with a driver or if it
has to be linked with a hardware device ?

You don't have to use a device driver for this. You need a device
driver only if you want to be portable to systems with a user/kernel
space separation or avoid link time dependencies. You can define a
simple API with normal functions for your MRAM device.
