dmaengine: mediatek: Add MediaTek High-Speed DMA controller for MT7622 and MT7623 SoC

2018-03-27T09:48:15+00:00

MediaTek High-Speed DMA controller (HSDMA) on MT7622 and MT7623 SoC has a single ring is dedicated to memory-to-memory transfer through ring based descriptor management. Even though there is only one physical ring available inside HSDMA, the driver can be easily extended to the support of multiple virtual channels processing simultaneously by means of DMA_VIRTUAL_CHANNELS effort.

dmaengine: Introduce DW AXI DMAC driver

2018-03-19T08:08:16+00:00

This patch adds support for the DW AXI DMAC controller. DW AXI DMAC is a part of HSDK development board from Synopsys. In this driver implementation only DMA_MEMCPY transfers are supported. Signed-off-by: Eugeniy Paltsev Signed-off-by: Vinod Koul

This patch adds the DMA controller driver for Spreadtrum SC9860 platform. Signed-off-by: Baolin Wang Signed-off-by: Vinod Koul

dmaengine: Build bcm-sba-raid driver as loadable module for iProc SoCs

2017-10-23T06:05:47+00:00

By default, we build Broadcom SBA RAID driver as loadable module for iProc SOCs so that kernel image is little smaller and we load SBA RAID driver only when required. Signed-off-by: Anup Patel Reviewed-by: Scott Branden Signed-off-by: Vinod Koul

dmaengine: stm32_mdma: add CONFIG_OF dependency

2017-10-12T14:03:55+00:00

Without CONFIG_OF we get a build warning: warning: (STM32_MDMA) selects DMA_OF which has unmet direct dependencies (DMADEVICES && OF) This adds a dependency on CONFIG_OF. Since this means we no longer need to select 'DMA_OF', I'm dropping that line as well. Fixes: a4ffb13c8946 ("dmaengine: Add STM32 MDMA driver") Signed-off-by: Arnd Bergmann Signed-off-by: Vinod Koul

dmaengine: Add STM32 MDMA driver

2017-10-08T09:15:34+00:00

This patch adds the driver for the STM32 MDMA controller. Master Direct memory access (MDMA) is used in order to provide high-speed data transfer between memory and memory or between peripherals and memory. MDMA controller provides a master AXI interface for main memory and peripheral registers access (system access port) and a master AHB interface only for Cortex-M7 TCM memory access (TCM access port). MDMA works in conjunction with the standard DMA controllers (DMA1 or DMA2). It offers up to 64 channels, each dedicated to managing memory access requests from one of the DMA stream memory buffer or other peripherals (w/ integrated FIFO).

dmaengine: Add STM32 DMAMUX driver

2017-09-27T10:31:35+00:00

This patch implements the STM32 DMAMUX driver. The DMAMUX request multiplexer allows routing a DMA request line between the peripherals and the DMA controllers of the product. The routing function is ensured by a programmable multi-channel DMA request line multiplexer. Each channel selects a unique DMA request line, unconditionally or synchronously with events from its DMAMUX synchronization inputs. The DMAMUX may also be used as a DMA request generator from programmable events on its input trigger signals Signed-off-by: M'boumba Cedric Madianga Signed-off-by: Pierre-Yves MORDRET Signed-off-by: Vinod Koul
