bool "Enable Driver Model for DMA drivers"
depends on DM
help
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.

dma: ti: add driver to K3 UDMA 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>
