This needs to be there as the original author is Channagoud Kadabi
and I'm the one who is modifying and upstreaming this driver.
It was suggested to have this kind of signature from the earlier 
patchset comments.

Can we do anything about this?

This is also, I will check if I can get rid of this by writing more in 
the description.
I don't really understand why do we need a paragraph here.

This file is not added in the dt-bindings as there are no properties 
(like reg-names or interrupts) for this driver
and anyway initialized from llcc driver.

Do we still need to have the Documentation in place?
