f8609c2b52 dw_dmac: use 'u32' for LLI structure members, not dma_addr_t
Use 'u32' for the LLI structure members, which are defined by hardware to be
32-bit. dma_addr_t is much more vague about its actual size.

41c556a8cb dma: mxs-dma: Export missing symbols from mxs-dma.c
mxs-dma.c provides two functions mxs_dma_is_apbh and mxs_dma_is_apbx
which are used at least in mxs-mmc.c. Building mxs-mmc as module
fails due to those two symbols not being exported.

6660f7af52 dma: tegra: do not set transfer desc flag to DMA_CTRL_ACK in cyclic mode
The sound dmaengine pcm driver uses the dma in cyclic mode and
it does not ack the transfer descriptor  after transfer stops.
This may lead to hold that desc in chip's dma driver and does
not allow to reuse/free that descriptors. Hence not enabling
flag DMA_CTRL_ACK when dma runs in cyclic mode.

fdec53d520 DMA: PL330: Fix racy mutex unlock
pl330_update() stores a pointer to the thrd->req that finished, which
contains a pointer to the corresponding pl330_req.  This is done with
the pl330_lock held.  Then, it iterates through the req_done list,
calling the callback for each of the requests that are done.  The
problem is that the driver releases the lock before calling the
callback for each of the callbacks.  pl330_submit_req() running in
another processor can then acquire the lock and insert another request
in one of the thrd->req that hasn't been processed yet, replacing the
pointer to pl330_req there.  When the callback returns in
pl330_update() and the next rqdone is popped from the list, it
dereferences the pl330_req pointer to the just scheduled pl330_req,
instead of the one that has finished, calling pl330 with the wrong r.

This patch fixes this by storing the pointer to pl330_req directly in
the list.

1dd1ea8eb4 dmaengine: at_hdmac: take maxburst from slave configuration
The maxburst/chunk size was taken from the private slave DMA data structure.
Use the common API provided by DMA_SLAVE_CONFIG to setup src/dst maxburst
values.
The ctrla field is not needed anymore in the slave private structure nor the
header constants that were located in an architecture specific directory.
The at91sam9g45_devices.c file that was using this platform data is also
modified to remove this now useless data.

Shawn Guo <shawn.guo@linaro.org> writes:

  I chose to base it on Sascha's imx-common-clk series than -rc, because
  otherwise it will keep patching clock file that has been removed by
  imx-common-clk series.  It also depends on imx-pinctrl pull-request
  I just sent to be functional.

  Note: when imx-common-clk and imx-pinctrl get merged together, the
  following files will have conflicts.  But the conflicts should not be
  so hard to resolve.
