Merge branches 'pm-tools' and 'pm-docs'

Merge power management utilities and documentation updates for 6.3-rc1:

 - Modify some power management utilities to use the canonical ftrace
   path (Ross Zwisler).

 - Correct spelling problems for Documentation/power/ as reported by
   codespell (Randy Dunlap).

* pm-tools:
  PM: tools: use canonical ftrace path

* pm-docs:
  Documentation: power: correct spelling

 controller needs to be enabled to receive signals from the line in question.
 After wakeup, it generally is better to disable that input to prevent the
 dedicated controller from triggering interrupts unnecessarily.
