Hi, Herbert, CAAM has the ability to provide DMA services. This is helpful for platforms that don't have a dedicated DMA hardware block. In this particular example, caam being a crypto accelerator at its fundamentals, where is recommended to add a caam-dma engine implementation, in drivers/dma or in drivers/crypto? Are the any rules/guidelines? I noticed that CCP already registered DMA services, the driver being held in drivers/crypto.
