10 DMA engines can do asynchronous data transfers without
11 involving the host CPU. Currently, this framework can be
12 used to offload memory copies in the network stack and
13 RAID operations in the MD driver. This menu only presents
14 DMA Device drivers supported by the configured arch, it may
15 be empty in some cases.

617 various audio clients in the Tegra210 audio processing engine
618 (APE). This DMA controller transfers data from memory to
619 peripheral and vice versa. It does not support memory to
620 memory data transfer.

667 AXI VDMA engine provides high-bandwidth direct memory access
668 between memory and AXI4-Stream video type target
669 peripherals including peripherals which support AXI4-
670 Stream Video Protocol. It has two stream interfaces/
671 channels, Memory Mapped to Stream (MM2S) and Stream to
672 Memory Mapped (S2MM) for the data transfers.
673 AXI CDMA engine provides high-bandwidth direct memory access
674 between a memory-mapped source address and a memory-mapped
675 destination address.
676 AXI DMA engine provides high-bandwidth one dimensional direct
677 memory access between memory and AXI4-Stream target peripherals.
678 AXI MCDMA engine provides high-bandwidth direct memory access
679 between memory and AXI4-Stream target peripherals. It provides
680 the scatter gather interface with multiple channels independent
681 configuration support.
