dmaengine: Remove FSF mailing addresses

2015-03-16T16:58:15+00:00

Free Software Foundation mailing address has been moved in the past and some of the addresses here are outdated. Remove them from file headers since the COPYING file in the kernel sources includes it. Signed-off-by: Jarkko Nikula Signed-off-by: Vinod Koul

dmaengine: Remove net_dma_find_channel

2015-03-05T16:16:48+00:00

Since commit 7bced397510a ("net_dma: simple removal") removed the net_dma support entirely, net_dma_find_channel has no users left. Remove the function entirely. Signed-off-by: Maxime Ripard Signed-off-by: Vinod Koul

dmaengine: Remove net_dma leftovers

2015-03-05T16:16:48+00:00

Commit 7bce d397 510a ("net_dma: simple removal") removed the net_dma support entirely but left some functions and prototypes in the dmaengine header. Remove them. Signed-off-by: Maxime Ripard Signed-off-by: Vinod Koul

dmaengine: Remove memset leftovers

2015-03-04T12:32:04+00:00

Commit 48a9db462d99 ("drivers/dma: remove unused support for MEMSET operations") removed support for the memset operation in dmaengine, but left the fill_aligned field that was supposed to set the buffer alignment for the memset operations. Remove that field too. Signed-off-by: Maxime Ripard Signed-off-by: Vinod Koul

dmaengine: Add dma_get_slave_caps() inline stub when !CONFIG_DMA_ENGINE

2015-01-19T13:02:51+00:00

Commit 0d5484b1c3db8a38 ("dmaengine: Move dma_get_slave_caps() implementation to dmaengine.c") turned the inline dma_get_slave_caps() function into an external function without adding an inline stub for the cases where CONFIG_DMA_ENGINE isn't set. This breaks compilation of drivers using the DMA engine API when CONFIG_DMA_ENGINE isn't set. Add an inline stub to fix compilation.

dmaengine: Move dma_get_slave_caps() implementation to dmaengine.c

2015-01-18T14:25:57+00:00

The function is too big to be a static inline. Signed-off-by: Laurent Pinchart Signed-off-by: Vinod Koul

dmaengine: Add 16 bytes, 32 bytes and 64 bytes bus widths

The widths are missing, add them. Signed-off-by: Laurent Pinchart Tested-by: Kuninori Morimoto Tested-by: Wolfram Sang

dmaengine: Remove device_control and device_slave_caps

2014-12-22T07:04:22+00:00

Now that device_control has been split into several functions, and device_slave_caps rendered useless, we can safely remove them. Signed-off-by: Maxime Ripard Acked-by: Laurent Pinchart Signed-off-by: Vinod Koul

dmaengine: Create a generic dma_slave_caps callback

2014-12-22T06:58:56+00:00

dma_slave_caps is very important to the generic layers that might interact with dmaengine, such as ASoC. Unfortunately, it has been added as yet another dma_device callback, and most of the existing drivers haven't implemented it, reducing its reliability. Introduce a generic behaviour to implement this, that rely on both the split of device_control to derive which functions are supported and on new variables to be set in the dma_device structure. These variables holds what used to be the capabilities, that were set per-channel. However, this proved to be a bit overkill, since every driver filling these so far were hardcoding it, disregarding which channel was actually given.
