At my previous job I had to write a device driver for a (simple) I2C device. I already had experience writing drivers for microcontrollers, but to move to Linux I found it was pretty simple to take the code for an existing device that was similar to what I wanted to do and use it as a reference. If you look at the code for a simple serial port [1], with the knowledge gained in the article, you would probably figure out what are the different parts.
