From e891009857716e17129899fe6345e7968010917f Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Tue, 13 Apr 2021 12:57:12 +0200 Subject: media: atmel: atmel-isc: add DMA to register offsets The DMA submodule is a part of the atmel-isc pipeline, and stands for Direct Memory Access. It acts like a master on the AXI bus of the SoC, and can directly write the RAM area with the pixel data from the ISC internal sram. Add dma to the reg offsets struct. This will allow different products to have a different reg offset for this particular module.
