andrzej-kaczmarek opened a new pull request #1320: Fix handling of PWM instances in nRF52 MCU/BSP
URL: https://github.com/apache/mynewt-core/pull/1320
 
 
   Original code allocated separate `int` for each instance id. After nRF52 refactoring this was changed to single `int` created on stack but since initialization is not done immediately when device is created, this pointer is invalid when actual initialization takes place.
   
   To avoid creating redundant global variables for each PWM instance we allow to pass instance id as simple in casted to pointer. Some helper macros were added to make this easier - such macros are already used in projects as Zephyr or BlueZ and are very convenient way to pass simple integers via user-data pointers.
