It's not at all about whether the Linux codein drivers/of supports this or not, adding it would be trivial. The point is that it would be *wrong* to add it because there already exists a way to identify every resource in the device tree and we should not extend that interface to have multiple ways to do the same thing just for convenience of a few device drivers! One of the important advantages of using the IEEE device tree bindings is that we can define device trees that are to a large degree compatible with how AIX, Solaris, MacOS, FreeBSD and probably many more (lesser known) operating systems probe their systems. Changing the resource interface in Linux to have two 'name' fields would also be terribly confusing and is not a good interface, it would just solve another problem (silly entries in /proc/iomem) that we don't need to have in the first place when we do the obvious conversion of the drivers to the IEEE standard way of doing this.
