Browse source 
Biggest changes in this set include the introduction of a new Intel 8254
 interface library module and the refactoring of the existing 104-quad-8
 modules to migrate it to the regmap API. Some other minor cleanups
 touching tools/counter and stm32-timer-cnt are also present.
 
 Changes
 * 104-quad-8
   - Remove reference in Kconfig to 25-bit counter value
   - Utilize bitfield access macros
   - Refactor to buffer states for CMR, IOR, and IDR
   - Utilize helper functions to handle PR, FLAG and PSC
   - Migrate to the regmap API
 * i8254
   - Introduce the Intel 8254 interface library module
 * stm32-timer-cnt
   - Reset TIM_TISEL to its default value in probe
 * tools/counter
   - Add .gitignore
   - Remove lingering 'include' directories on make clean
