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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
