dmaengine: dw: went back to plain {request,free}_irq() calls

2014-05-07T10:04:45Z

The commit dbde5c29 "dw_dmac: use devm_* functions to simplify code" turns probe function to use devm_* helpers and simultaneously brings a regression. We need to ensure irq is disabled, followed by ensuring that don't schedule any more tasklets and then its safe to use tasklet_kill(). The free_irq() will ensure that the irq is disabled and also wait till all scheduled interrupts are executed by invoking synchronize_irq(). So we need to only do tasklet_kill() after invoking free_irq(). Signed-off-by: Andy Shevchenko Cc: stable@vger.kernel.org # v3.11+ Signed-off-by: Vinod Koul

dma: dw: allocate memory in two stages in probe

2014-03-26T06:14:27Z

This makes the probe() function a little bit clearer. Signed-off-by: Andy Shevchenko Signed-off-by: Vinod Koul

dma: dw: remove leftovers in the comment blocks

2014-02-17T08:46:54Z

There is couple of leftovers in the comment blocks. This patch modifies the comments accordingly. There is no functional change. Signed-off-by: Andy Shevchenko Signed-off-by: Vinod Koul

dma: dw: use %pad instead of casting dma_addr_t

2014-01-20T08:26:37Z

Since we have nice helper to print dma_addr_t values by reference we may use it instead of explicit casting to a longest type. Signed-off-by: Andy Shevchenko Signed-off-by: Vinod Koul

dma: dw: join split up messages

2014-01-20T08:26:37Z

The joined messages are better to grep when debugging. There is no functional change. Signed-off-by: Andy Shevchenko Signed-off-by: Vinod Koul

dma: dw: fix style of multiline comment

2014-01-20T08:26:37Z

Simple fix a style of the multiline comment. There is no functional change. Signed-off-by: Andy Shevchenko Signed-off-by: Vinod Koul

Merge commit 'dmaengine-3.13-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/dmaengine

2013-11-16T06:32:36Z

Pull dmaengine changes from Dan 1/ Bartlomiej and Dan finalized a rework of the dma address unmap implementation. 2/ In the course of testing 1/ a collection of enhancements to dmatest fell out. Notably basic performance statistics, and fixed / enhanced test control through new module parameters 'run', 'wait', 'noverify', and 'verbose'. Thanks to Andriy and Linus for their review. 3/ Testing the raid related corner cases of 1/ triggered bugs in the recently added 16-source operation support in the ioatdma driver. 4/ Some minor fixes / cleanups to mv_xor and ioatdma.

dmaengine: remove DMA unmap from drivers

2013-11-14T19:04:38Z

Remove support for DMA unmapping from drivers as it is no longer needed (DMA core code is now handling it).

dmaengine: prepare for generic 'unmap' data

2013-11-14T00:25:06Z

Add a hook for a common dma unmap implementation to enable removal of the per driver custom unmap code. (A reworked version of Bartlomiej Zolnierkiewicz's patches to remove the custom callbacks and the size increase of dma_async_tx_descriptor for drivers that don't care about raid).
