Commit Message

Eugen Hristev April 5, 2021, 3:50 p.m. UTC
Create a product specific callback for initializing the GAM submodule
of the pipeline.
For sama5d2 product, there is no special configuration at this moment,
thus this function is a noop.

Changes in v2:
- addded function prototype to avoid warning with W=1
