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.
