A couple of clarifications about the time units for the deadline
parameters uncovered in the discussion around
https://lore.kernel.org/lkml/3c726cf5-0c94-4cc6-aff0-a453d840d452@arm.com/

While at it I changed the documentation example to chrt instead
of the schedtool fork.

No functional changes.

Christian Loehle (4):
  sched/deadline: Convert schedtool example to chrt
  sched/deadline: Clarify nanoseconds in uapi
  cpufreq/cppc: Use NSEC_PER_MSEC for deadline task
  sched/cpufreq: Use NSEC_PER_MSEC for deadline task
