dma: pl330: Convert to devm_ioremap_resource()

2013-04-15T04:21:18+00:00

Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.

DMA: PL330: allow submitting 2 requests at a time

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

Fix the logic to allow mc programming of second transfer after first
has been done, by removing immediate return upon success and iterating
until we detect QFull or DMAC dying.

DMA: PL330: Add check if device tree compatible

2013-04-02T17:41:04+00:00

This patch register the dma controller with generic dma helpers only
in DT case. This also adds some extra error handling in the driver.

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: PL330: Register the DMA controller with the generic DMA helpers

This patch registers the pl330 dma controller driver with the generic
device tree dma helper functions.

DMA: PL330: Add xlate function

2013-02-14T14:34:27+00:00

Add xlate to translate the device-tree binding information into
the appropriate format. The filter function requires the dma
controller device and dma channel number as filter_params.

DMA: PL330: Add new pl330 filter for DT case.

2013-02-14T14:34:27+00:00

This patch adds a new pl330_dt_filter for DT case to filter the
required channel based on the new filter params and modifies the
old filter only for non-DT case as suggested by Arnd Bergmann.

DMA: PL330: Use devm_* functions

2013-01-08T06:05:04+00:00

devm_* functions are device managed and make the code and error
handling a bit simpler.

Drivers: dma: remove __dev* attributes.

2013-01-03T23:57:15+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitconst,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

dma: remove use of __devinit

2012-11-28T20:42:36+00:00

CONFIG_HOTPLUG is going away as an option so __devinit is no longer
needed.
