dmaengine: fsldma: simplify getting .drvdata

2018-04-22T16:07:17Z

We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang Signed-off-by: Vinod Koul

dmaengine: fsldma: set BWC, DAHTS and SAHTS values correctly

2017-06-22T13:01:35Z

The bits of BWC, DAHTS and SAHTS in the DMA mode register must be cleared before a new value can be or-ed in. Signed-off-by: Thomas Breitung Signed-off-by: Wolfgang Ocker Signed-off-by: Vinod Koul

dmaengine: NO_IRQ removal from powerpc-only drivers

2016-09-14T13:27:38Z

We'd like to eventually remove NO_IRQ on powerpc, so remove usages of it from powerpc-only drivers. Signed-off-by: Michael Ellerman Signed-off-by: Vinod Koul

dmaengine: fsldma: move unmap to before callback

2016-08-08T02:41:43Z

Completion callback should happen after dma_descriptor_unmap() has happened. This allow the cache invalidate to happen and ensure that the data accessed by the upper layer is in memory that was from DMA rather than stale data. On some architecture this is done by the hardware, however we should make the code consistent to not cause confusion. Signed-off-by: Dave Jiang Acked-by: Li Yang Signed-off-by: Vinod Koul

dmaengine: fsldma: convert callback to helper function

2016-08-08T02:41:39Z

This is in preperation of moving to a callback that provides results to the callback for the transaction. The conversion will maintain current behavior and the driver must convert to new callback mechanism at a later time in order to receive results.

dmaengine: Remove site specific OOM error messages on kzalloc

2016-06-21T16:05:00Z

If kzalloc() fails it will issue it's own error message including a dump_stack(). So remove the site specific error messages. Signed-off-by: Peter Griffin Acked-by: Jon Hunter Acked-by: Linus Walleij Signed-off-by: Vinod Koul
