This is a proof that SUBSYS_1300XXXX is not a binding. Your driver does
not use it.

Drop all such things which are not used by drivers or explain why they
are needed to be in the binding - what do they bind.

I asked for this already, for exactly the same thing.


I did not check the rest, so next time I will choose any other random
define and if I do not find it explained nor used, I will question it.
Because you tend to apply pieces of review instead of really change your
code.
