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] Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
