---
Changes in v5:
- Make the array static const
Changes in v4:
- Use a terminating entry in the array for getting node type for controller
Changes in v3:
- Modify the Makefile to remove comparison
- Put the supported controllers in array and checking from array
Changes in v2:
- Remove the #defines from the patch and adding controller support
