dmaengine: ppc4xx: remove DRIVER_ATTR() usage

2017-07-21T06:32:49+00:00

It's better to be explicit and use the DRIVER_ATTR_RW() and DRIVER_ATTR_RO() macros when defining a driver's sysfs file. Bonus is this fixes up a checkpatch.pl warning. This is part of a series to drop DRIVER_ATTR() from the tree entirely. Cc: Vinod Koul Cc: Dan Williams Signed-off-by: Greg Kroah-Hartman Signed-off-by: Vinod Koul

dmaengine: Convert to using %pOF instead of full_name

2017-07-19T04:00:44+00:00

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by: Rob Herring Cc: Vinod Koul Cc: Dan Williams Cc: dmaengine@vger.kernel.org Signed-off-by: Vinod Koul

dmaengine: NO_IRQ removal from powerpc-only drivers

2016-09-14T13:27:38+00:00

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: ppc4xx/adma: move unmap to before callback

2016-08-08T02:41:43+00:00

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 Signed-off-by: Vinod Koul

dmaengine: ppc4xx_adma: convert callback to helper function

2016-08-08T02:41:40+00:00

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

2016-06-21T16:05:00+00:00

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

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Free Software Foundation mailing address has been moved in the past and some of the addresses here are outdated.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
