Subject[GIT PULL] dmaengine updates for 4.3-rc1
Hi Linus,

Here is the dmaengine update for 4.3-rc1.


The following changes since commit d770e558e21961ad6cfdf0ff7df0eb5d7d4f0754:

Linux 4.2-rc1 (2015-07-05 11:01:52 -0700)

are available in the git repository at:

git://git.infradead.org/users/vkoul/slave-dma.git tags/dmaengine-4.3-rc1

dmaengine: ioatdma: add Broadwell EP ioatdma PCI dev IDs (2015-08-28 10:06:06 +0530)

----------------------------------------------------------------
dmaengine updates for 4.3-rc1

This time we have aded a new capability for scatter-gathered memset using
dmaengine APIs. This is supported in xdmac & hdmac drivers

We have added support for reusing descriptors for examples like video
buffers etc. Driver will follow

The behaviour of descriptor ack has been clarified and documented

New devices added are:
- dma controller in sun[457]i SoCs
- lpc18xx dmamux
- ZTE ZX296702 dma controller
- Analog Devices AXI-DMAC DMA controller
- eDMA support for dma-crossbar
- imx6sx support in imx-sdma driver
- imx-sdma device to device support

Others
- jz4780 fixes
- ioatdma large refactor and cleanup for removal of ioat v1 and v2 which is
deprecated and fixes
- ACPI support in X-Gene DMA engine driver
- ipu irq fixes
- mvxor fixes
- minor fixes spread thru drivers
