ARM/dmaengine: pl08x: pass reasonable memcpy settings

2017-05-24T04:14:32+00:00

We cannot use bits from configuration registers as API between platforms and driver like this, abstract it out to two enums and mimic the stuff passed as device tree data. This is done to make it possible for the driver to generate the ccfg word on-the-fly so we can support more PL08x derivatives.

dmaengine: pl08x: Add support for the DMA slave map

2016-11-17T10:21:28+00:00

This patch adds support for the new channel request API introduced in commit a8135d0d79e9d0ad3a4ff494fceeaae83 "dmaengine: core: Introduce new, universal API to request a channel". param field of struct dma_slave_map type entries in the platform data structure should be pointing to struct pl08x_channel_data of related DMA channel.

dmaengine: pl08x: allocate OF slave channel data at probe time

2016-04-05T23:53:41+00:00

The current OF translation of channels can never work with any DMA client using the DMA channels directly: the only way to get the channels initialized properly is in the dma_async_device_register() call, where chan->dev etc is allocated and initialized. Allocate and initialize all possible DMA channels and only augment a target channel with the periph_buses at of_xlate(). Remove some const settings to make things work.

dmaengine: PL08x: Avoid collisions with get_signal() macro

2013-07-05T06:10:47+00:00

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

2012-07-01T13:15:48+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. Acked-by: Linus Walleij Tested-by: Linus Walleij Signed-off-by: Russell King

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

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

2012-07-01T13:15:38+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(). Tested-by: Linus Walleij Signed-off-by: Russell King

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