dma: Add Xilinx AXI Video Direct Memory Access Engine driver support

2014-04-30T05:14:13Z

This is the driver for the AXI Video Direct Memory Access (AXI VDMA) core, which is a soft Xilinx IP core that provides high- bandwidth direct memory access between memory and AXI4-Stream type video target peripherals. The core provides efficient two dimensional DMA operations with independent asynchronous read and write channel operation. This module works on Zynq (ARM Based SoC) and Microblaze platforms.

dmaengine: add Qualcomm BAM dma driver

2014-04-05T15:14:26Z

Add the DMA engine driver for the QCOM Bus Access Manager (BAM) DMA controller found in the MSM 8x74 platforms. Each BAM DMA device is associated with a specific on-chip peripheral. Each channel provides a uni-directional data transfer engine that is capable of transferring data between the peripheral and system memory (System mode), or between two peripherals (BAM2BAM). The initial release of this driver only supports slave transfers between peripherals and system memory. Signed-off-by: Andy Gross Tested-by: Stanimir Varbanov Signed-off-by: Vinod Koul

dmaengine: Add MOXA ART DMA engine driver

2014-01-20T07:02:46Z

The MOXA ART SoC has a DMA controller capable of offloading expensive memory operations, such as large copies. This patch adds support for the controller including four channels. Two of these are used to handle MMC copy on the UC-7112-LX hardware. The remaining two can be used in a future audio driver or client application.

dmaengine: add driver for Samsung s3c24xx SoCs

2013-10-07T21:42:10Z

This adds a new driver to support the s3c24xx dma using the dmaengine and makes the old one in mach-s3c24xx obsolete in the long run. Conceptually the s3c24xx-dma feels like a distant relative of the pl08x with numerous virtual channels being mapped to a lot less physical ones. The driver therefore borrows a lot from the amba-pl08x driver in this regard. Functionality-wise the driver gains a memcpy ability in addition to the slave_sg one. The driver supports both the method for requesting the peripheral used by SoCs before the S3C2443 and the different method for S3C2443 and later. On earlier SoCs the hardware channels usable for specific peripherals is constrainted while on later SoCs all channels can be used for any peripheral. Tested on a s3c2416-based board, memcpy using the dmatest module and slave_sg partially using the spi-s3c64xx driver.

usb: musb dma: add cppi41 dma driver

2013-08-09T14:40:16Z

This driver is currently used by musb' cppi41 couter part. I may merge both dma engine user of musb at some point but not just yet. The driver seems to work in RX/TX mode in host mode, tested on mass storage. I increaed the size of the TX / RX transfers and waited for the core code to cancel a transfers and it seems to recover. v2..3: - use mall transfers on RX side and check data toggle. - use rndis mode on tx side so we haveon interrupt for 4096 transfers. - remove custom "transferred" hack and use dmaengine_tx_status() to compute the total amount of data that has been transferred. - cancel transfers and reclaim descriptors v1..v2: - RX path added - dma mode 0 & 1 is working - device tree nodes re-created.

dma: Add a jz4740 dmaengine driver

2013-07-05T06:10:50Z

This patch adds dmaengine support for the JZ4740 DMA controller. For now the driver will be a wrapper around the custom JZ4740 DMA API. Once all users of the custom JZ4740 DMA API have been converted to the dmaengine API the custom API will be removed and direct hardware access will be added to the dmaengine driver.
