  counter: add defaults to switch-statements (2022-03-04 09:30:38 -0500)

----------------------------------------------------------------
First set of new Counter updates, cleanups, and features for 5.18

Only a few changes this cycle, but we do see the addition of a new
COUNTER_EVENT_CHANGE_OF_STATE event type that allows userspace to watch
counter pulses.

Features
* Add new COUNTER_EVENT_CHANGE_OF_STATE. This adds new counter event to
  notify user space about every new counter pulse. The interrupt-cnt
  driver is the first to use this new feature.

Cleanups
- Add Counter subsystem git tree to MAINTAINERS file.
- Set counter device name. This provides a convenient way to identify
  the counter device in devres_log events and similar situations.
- Add defaults to switch-statements. This pacifies warning messages from
  Clang static analysis reports.

Driver Updates
* 104-quad-8
  - Add COMPILE_TEST depends
* interrupt-cnt
  - Add counter_push_event()
