Sorry I missed your reply. However, you didn't address these comments:

To rephrase this, a protocol does not fully describe the h/w and DT should describe the h/w.
Also, you should include the interrupt whether you use it in the driver currently or not. Again, it's about describing the h/w, not what a driver happens to use ATM.
