dmaengine: PL08x: Avoid collisions with get_signal() macro

2013-07-05T06:10:47Z

As pointed out by Arnd Bergmann there is a get_signal macro definied in linux/signal.h which can conflict with the platform data callback function of the same name leading to confusing errors from the compiler (especially if signal.h manages to get pulled into the driver itself due to header dependencies). Avoid such errors by renaming get_signal and put_signal in the platform data to get_xfer_signal and put_xfer_signal. Signed-off-by: Mark Brown Acked-by: Arnd Bergmann Signed-off-by: Vinod Koul

dmaengine: PL08x: get rid of unnecessary checks in dma_slave_config

2012-07-01T13:15:48Z

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. Acked-by: Linus Walleij Tested-by: Linus Walleij Signed-off-by: Russell King

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

2012-07-01T13:15:40Z

Move the driver private data structures into the driver itself, rather than having them exposed to everyone in a header file. Acked-by: Linus Walleij Tested-by: Linus Walleij Signed-off-by: Russell King

dmaengine: PL08x: clean up get_signal/put_signal

2012-07-01T13:15:38Z

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(). Tested-by: Linus Walleij Signed-off-by: Russell King

dmaengine: PL08x: remove circular_buffer boolean from channel data

2012-07-01T13:15:37Z

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. Acked-by: Linus Walleij Tested-by: Linus Walleij Signed-off-by: Russell King

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

2012-04-25T09:51:47Z

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

2012-03-13T06:06:06Z

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

2012-02-22T12:45:37Z

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. Signed-off-by: Viresh Kumar Acked-by: Linus Walleij Signed-off-by: Vinod Koul
