Subject: Time: new clocksource

Hi All,

We have a Digital PLL with 64 bit timer counter hardware and the
counter is accessible from the CPU over the PCIe bus.

Is it possible to add this timer counter hardware as new clocksource
driver? To do this, can someone please point me to the existing
reference source code(or patch) for this task.

Suppose if it is possible to add a new clocksource driver for this
hardware then does any userspace get_timestamp* API would get the time
from this new hardware?

Thanks,
Sekhar
