Yes, that's already covered in the binding.

I don't see how this is possible. The CNTACRn register controls secure
vs. non-secure access for particular registers in a frame regardless of
which view is used. The CNTPL0ACRn is not a security restricted register
and it can only restrict access to certain registers in the second view.
No combination of settings in these registers can restrict access to
only the second view in a frame with two views.
