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 DMA_LPC32XX bool "LPC32XX DMA driver" select DMA_LEGACY help Enable some legacy DMA code for lpc32xx. It provides some direct functions likes lpc32xx_dma_wait_status() which can be called from other code. This should be converted to use driver model and UCLASS_DMA. config TI_EDMA3 bool "TI EDMA3 driver" 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. 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" default y if FSLDMAFEC 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. source "drivers/dma/ti/Kconfig" endmenu # menu "DMA Support"
