[PATCH v3 25/33] media: atmel: atmel-isc: create an adapt pipeline callback for product specific

From: Eugen Hristev
Date: Tue Apr 13 2021 - 07:04:08 EST


Once the pipeline is set in the base code, create a callback that will adapt
the ISC pipeline to each product.
Create the adapt_pipeline callback that will be used in this fashion.
