A cleaner way is how we are doing irqchips [1]. This needs a single function (or one each for clksrc and clkevt) that has a DT match list of all known timers and calls their init function. It should be a bit simpler than irqchips init function because you don't need to worry about hierarchy init ordering. That doesn't solve non-DT though and if there are any extra functions like we have with irqchips, you still need the header in include/linux.
