The UDMA-P is intended to perform similar (but significantly upgraded) functions as the packet-oriented DMA used on previous SoC devices. The UDMA-P module supports the transmission and reception of various packet types. The UDMA-P also supports acting as both a UTC and UDMA-C for its internal channels. Channels in the UDMA-P can be configured to be either Packet-Based or Third-Party channels on a channel by channel basis. The initial driver supports: - MEM_TO_MEM (TR mode) - DEV_TO_MEM (Packet mode) - MEM_TO_DEV (Packet mode) Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Vignesh R <vigneshr@ti.com>

Enable driver model for DMA. DMA engines can do
|
|
asynchronous data transfers without involving the host
|
|
CPU. Currently, this framework can be used to offload
|
|
memory copies to and from devices like qspi, ethernet
|
|
etc Drivers provide methods to access the DMA devices
|
|
buses that is used to transfer data to and from memory.

The uclass interface is defined in include/dma.h.
