MPIC Timers as clocksource

MPIC Timers as clocksource

[Régis Odeyé]

Hi everybody,
Is there anyone who implemented a clocksource driver 
(drivers/clocksource) to deal with the MPIC timers especially with 86xx 
and 85xx soc's ?
Regards.

We have a plan to use an external clock signal to drive those timers. 
This signal is common with other boards in a same enclosure so we could 
synchronize our boards with those timers.
Could you point me out to the related code even if there is some 
adaptations to get a clocksource driver.
Regards.

I'll post some code.

As for clocksource.. last time I looked at that it was more about =20
using a timer as the single kernel reference clock.
