Subject: [PATCH 167/247] media: atmel: atmel-isc: add SUB422 and SUB420 to
|
|
register offsets
|
|
|
|
The SUB submodules are a part of the atmel-isc pipeline, and stand for
|
|
Subsampling. They are used to subsample the original YUV 4:4:4 pixel ratio
|
|
aspect to either 4:2:2 or 4:2:0.
|
|
Add sub420 and sub422 to the reg offsets struct.
|
|
This will allow different products to have a different reg offset for these
|
|
particular modules.
