dmaengine: PL08x: get rid of unnecessary checks in dma_slave_config

2012-07-01T13:15:48+00:00

Get rid of the unnecessary checks in dma_slave_config utilizing
the DMA direction.  This allows us to move the computation of
cctl to the prepare function.

dmaengine: PL08x: move private data structures into amba-pl08x.c

2012-07-01T13:15:40+00:00

Move the driver private data structures into the driver itself, rather
than having them exposed to everyone in a header file.

dmaengine: PL08x: clean up get_signal/put_signal

2012-07-01T13:15:38+00:00

Try to avoid dereferencing the DMA engine's channel struct in these
platform helpers; instead, pass a pointer to the channel data into
get_signal(), and the returned signal number to put_signal().

dmaengine: PL08x: remove circular_buffer boolean from channel data

2012-07-01T13:15:37+00:00

Circular buffers are not handled in this way; we have a separate API
call now to setup circular buffers.  So lets not mislead people with
this bool.

dma/amba-pl08x: add support for the Nomadik variant

2012-04-25T09:51:47+00:00

The Nomadik PL080 variant has some extra protection bits that
may be set, so we need to check these bits to see if the
channels are actually available for the DMAengine to use.

dmaengine: move last completed cookie into generic dma_chan structure

2012-03-13T06:06:06+00:00

Every DMA engine implementation declares a last completed dma cookie
in their private dma channel structures.  This is pointless, and
forces driver specific code.  Move this out into the common dma_chan
structure.

dmaengine/amba-pl08x: Take flow controller info from DMA_SLAVE_CONFIG

2012-02-22T12:45:37+00:00

Flow controller information is passed now from DMA_SLAVE_CONFIG option. This
patch makes changes in pl08x driver to use device_fc from it instead of platform
data.

dmaengine/amba-pl08x: Add support for sg len greater than one for slave transfers

2011-09-19T09:43:06+00:00

Untill now, sg_len greater than one is not supported. This patch adds support to
do that.

Note: Still, if peripheral is flow controller, sg_len can't be greater that one.
