menu "DMA Support"
config DMA
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.
config DMA_CHANNELS
bool "Enable DMA channels support"
depends on DMA
help
Enable channels support for DMA. Some DMA controllers have multiple
channels which can either transfer data to/from different devices.
config SANDBOX_DMA
bool "Enable the sandbox DMA test driver"
depends on DMA && DMA_CHANNELS && SANDBOX
help
Enable support for a test DMA uclass implementation. It stimulates
DMA transfer by simple copying data between channels.
config BCM6348_IUDMA
bool "BCM6348 IUDMA driver"
depends on ARCH_BMIPS
select DMA_CHANNELS
help
Enable the BCM6348 IUDMA driver.
This driver support data transfer from devices to
memory and from memory to devices.
config TI_EDMA3
bool "TI EDMA3 driver"
depends on ARCH_OMAP2PLUS || ARCH_KEYSTONE
select DMA_LEGACY
help
Enable the TI EDMA3 driver for DRA7xx and AM43xx evms.
This driver support data transfer between memory
regions.
config TI_KSNAV
bool "TI Keystone Navigator DMA driver"
depends on ARCH_KEYSTONE
default y
select DMA_LEGACY
help
Enable the Keystone Navigator driver for Keystone 2 platforms.
config APBH_DMA
bool "Support APBH DMA"
depends on MX23 || MX28 || MX6 || MX7 || IMX8 || IMX8M
select DMA_LEGACY
help
Enable APBH DMA driver.
config XILINX_DPDMA
bool "Enable ZynqMP Display Port DMA driver"
depends on DMA && ZYNQMP_POWER_DOMAIN
help
Enable support for Xilinx ZynqMP Display DMA driver. Currently
this file is used as placeholder for driver. The main reason is
to record compatible string and calling power domain driver.
config ADI_DMA
bool "ADI DMA driver"
depends on DMA && DMA_CHANNELS
help
Enable DMA support for Analog Devices SOCs, such as the SC5xx.
Currently this is a minimalistic driver tested against OSPI use only.
if APBH_DMA
config APBH_DMA_BURST
bool "Enable DMA BURST"
config APBH_DMA_BURST8
bool "Enable DMA BURST8"
endif
config DMA_LEGACY
bool "Legacy DMA support"
help
Enable legacy DMA support. This does not use driver model and should
be migrated to the new API.
It is required for some PowerPC boards.
