description: |
  C-SKY multi-processors timer is designed for C-SKY SMP system and the regs are
  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.
