Series [v3,01/33] media: atmel: atmel-isc: specialize gamma table into product specific | expand

Commit Message

Eugen Hristev April 13, 2021, 10:57 a.m. UTC
The dma configuration (DCFG) is specific to the product.
Move this configuration in the product specific driver, and add the
field inside the driver struct.
