dma: Add driver for ADI SC5xx-family SoC MDMA functionality

2025-03-12T16:24:58Z

Add a rudimentary MDMA driver for the Analog Devices SC5xx SoCs, primarily intended for use with and tested against the QSPI/OSPI IP included in the SoC.

dma: xilinx: Add Display Port DMA driver

2022-03-09T11:35:50Z

Display Port (DP) has own dma driver that's why add this skeleton driver only for handling power domain setting and send configuration object to PMUFW to enable it.

dma: ti: add driver to K3 UDMA

2019-04-12T00:07:12Z

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 Signed-off-by: Grygorii Strashko Signed-off-by: Vignesh R

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

dm: implement a DMA uclass

Incorporate DMA driver from legacy LPCLinux NXP BSP. The files taken from the legacy patch are: - lpc32xx DMA driver - lpc3250 header file DMA registers definition. The legacy driver was updated and clean-up as part of the integration with the latest u-boot. Signed-off-by: Sylvain Lemieux Acked-by: Marek Vasut Tested-by: Vladimir Zapolskiy

dma: ti-edma3: introduce edma3 driver

2014-10-23T15:27:29Z

The EDMA3 controller’s primary purpose is to service data transfers that you program between two memory-mapped slave endpoints on the device. Typical usage includes, but is not limited to the following: - Servicing software-driven paging transfers (e.g., transfers from external memory, such as SDRAM to internal device memory, such as DSP L2 SRAM) - Servicing event-driven peripherals, such as a serial port - Performing sorting or sub-frame extraction of various data structures - Offloading data transfers from the main device DSP(s) - See the device-specific data manual for specific peripherals that are accessible via the EDMA3 controller Signed-off-by: Ivan Khoronzhuk
