DESCRIPTION
Theclock driver uses the counter/timer facilities of
the MVME147's pcc driver or the MVME167/MVME177's
pcctwo driver to provide two independent hardware
clocks for use by the NetBSD kernel.
Both clock interrupts are set to 100Hz, with one used to provide the master kernel stats clock tick. The other is used for profiling purposes.
