[PATCH] ARM: dts: keystone: use one to one address translations under netcp

From: WingMan Kwok
Date: Tue Sep 01 2015 - 16:30:24 EST


Network subsystem NetCP in Keystone-2 devices includes some HW blocks
that are memory mapped to ranges outside that of the NetCP itself.
Thus address space of a child node of the NetCP node needs to be
mapped 1:1 onto the parent address space. Hence empty ranges
should be used under the NetCP node.
