coh901318: don't open-code simple_read_from_buffer()

2013-09-04T02:52:46+00:00

... and BTW, failing copy_to_user() means EFAULT, not EINVAL

dma: coh901318: add devicetree support

2013-06-17T11:54:27+00:00

This adds support for probing the COH 901 318 DMA controller
and channels from the device tree.

Contains portions of a sketch patch from Arnd Bergmann.

dma: Remove erroneous exit and exit_p() references

2013-04-15T04:21:16+00:00

Removing the annotation with __exit and referencing with __exit_p()
present in dma driver module remove hooks.

Part of the __devexit and __devexit_p() purge.

Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma

2013-02-26T17:24:48+00:00

Pull slave-dmaengine updates from Vinod Koul:
 "This is fairly big pull by my standards as I had missed last merge
  window.  So we have the support for device tree for slave-dmaengine,
  large updates to dw_dmac driver from Andy for reusing on different
  architectures.  Along with this we have fixes on bunch of the drivers"

Fix up trivial conflicts, usually due to #include line movement next to
each other.

dma: coh901318: set residue only if dma is in progress

2013-02-14T14:30:53+00:00

When status is DMA_SUCCESS the residue should be zero. Otherwise it's a bug.

dma: coh901318: cut down on platform data abstraction

2013-01-07T16:36:41+00:00

Since we merged the platform data into the driver we can
remove the middle-man abstraction.

dma: coh901318: merge header files

2013-01-07T16:36:37+00:00

We do not need two header files for the two parts of the driver
to talk to each other so merge them into one.

the main driver and the LLI portions into the driver, including
register definitions and such.
