I guess the real question is, how high resolution does a high resolution
timer need to be,
In the order of microseconds.
I think both the MPC52xx GPT0-7 and the SLT0-1 fulfil this fairly
easily.
There is some basic work for MPC5200 available:

I asked this earlier, but figured you might have a better insight. Is their value in having 'drivers' for more than one clock source? I'd say most (of not all) the PPC SoCs have timers on the system side that we could provide drivers for, I'm just not sure if that does anything for anyone.
