Subject: [GIT PULL] slave dmaengine updates for 4.5-rc1
Hi Linus,
Please pull to receive following updates from dmaengine tree for 4.5-rc1.
The following changes since commit 8005c49d9aea74d382f474ce11afbbc7d7130bec:
Linux 4.4-rc1 (2015-11-15 17:00:27 -0800)

dmaengine: mv_xor: add suspend/resume support (2016-01-06 15:42:27 +0530)
----------------------------------------------------------------
dmaengine updates for 4.5-rc1
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:
- 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
