*What I want to achieve :* I want to create a new driver that allows the user to open a device "/dev/mram" and use ioctl calls to allow the user to control these registers in a safe way.
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.
