C-SKY Multi-processors Timer
============================

C-SKY multi-processors timer is designed for C-SKY SMP system and the
regs is accessed by cpu co-processor 4 registers with mtcr/mfcr.

 - PTIM_CTLR "cr<0, 14>" Control reg to start reset timer.
 - PTIM_TSR  "cr<1, 14>" Interrupt cleanup status reg.
 - PTIM_CCVR "cr<3, 14>" Current counter value reg.
 - PTIM_LVR  "cr<6, 14>" Window value reg to trigger next event.
