Merge tag 'dmaengine-4.5-rc1' of git://git.infradead.org/users/vkoul/slave-dma

Pull dmaengine updates from Vinod Koul:
"This round we have few new features, new driver and updates to few
drivers.

The new features to dmaengine core are:
- Synchronized transfer termination API to terminate the dmaengine
transfers in synchronized and async fashion as required by users.
We have its user now in ALSA dmaengine lib, img, at_xdma, axi_dmac
drivers.
- Universal API for channel request and start consolidation of
request flows. It's user is ompa-dma driver.
- Introduce reuse of descriptors and use in pxa_dma driver

Add/Remove:
- New STM32 DMA driver
- Removal of unused R-Car HPB-DMAC driver

Updates:
- ti-dma-crossbar updates for supporting eDMA
- tegra-apb pm updates
- idma64
- mv_xor updates
- ste_dma updates"

dmaengine: virt-dma: don't always free descriptor upon completion

This patch attempts to enhance the case of a transfer submitted multiple
times, and where the cost of creating the descriptors chain is not
negligible.

This happens with big video buffers (several megabytes, ie. several
thousands of linked descriptors in one scatter-gather list). In these
cases, a video driver would want to do :
- tx = dmaengine_prep_slave_sg()
- dma_engine_submit(tx);
- dma_async_issue_pending()
- wait for video completion
- read video data (or not, skipping a frame is also possible)
- dma_engine_submit(tx)
=> here, the descriptors chain recalculation will take time
=> the dma coherent allocation over and over might create holes in
the dma pool, which is counter-productive.
- dma_async_issue_pending()
- etc ...

In order to cope with this case, virt-dma is modified to prevent freeing
the descriptors upon completion if DMA_CTRL_REUSE flag is set in the
transfer.

This patch is a respin of the former DMA_CTRL_ACK approach, which was
reverted due to a regression in audio drivers.
