Regular drivers do not to be OF-centric. This won't allow them to be used
outside of OF-only platforms.

Here I stop my review and recommend you first to review others' patches and
learn from other reviews. This will help you a lot with avoiding typical
mistakes.

Also Matti would be the best reviewer for this as he worked (still works?)
for ROHM and knows the HW a bit more than average kernel developer.
