- Subject: [PATCH 179/247] media: atmel: atmel-isc: create callback for RLP
- submodule product specific
- The RLP submodule is a part of the atmel-isc pipeline, and stands for
- Rounding,Limiting and Packaging. It used to extract specific data from the
- ISC pipeline. For example if we want to output greyscale 8 bit, we would
- use limiting to 8 bits, and packaging to Luma component only.
- Create a product specific callback for initializing the RLP submodule
- of the pipeline
- [hverkuil: made isc_sama5d2_config_rlp static]
