+Subject: [PATCH 165/247] media: atmel: atmel-isc: extract CBC submodule config
+ into separate function
+
+The CBC submodule is a part of the atmel-isc pipeline, and stands for
+Contrast Brightness Control. It is used to apply gains and offsets to the
+luma (Y) and chroma (U, V) components of the YUV elements.
+The CBC submodule should be initialized in the product specific driver
+as it's product specific. Other products can implement it differently
