Subject: [PATCH 162/247] media: atmel: atmel-isc: extract CSC submodule config
|
|
into separate function
|
|
|
|
The CSC submodule is a part of the atmel-isc pipeline, and stands for
|
|
Color Space Conversion. It is used to apply a matrix transformation to
|
|
RGB pixels to convert them to the YUV components.
|
|
The CSC submodule should be initialized in the product specific driver
|
|
as it's product specific. Other products can implement it differently.
