This is initial device tree support for the ARM Integrator family, we create a very basic device tree, #ifdef out the non-DT machines when compiling for device tree.

This is linux specific and a common issue we need a solution for. Grant had done something for versatile and we discussed it some, but nothing ever got close to finalized. IIRC, Grant's solution was just add a "linux,clockevent" or "linux,clocksource" to the nodes that are to be used. But he wasn't really happy with it. Perhaps using these names as aliases would be better. Rob
