This patch series (v1: http://www.spinics.net/lists/dmaengine/msg07930.html)
contains a number of mostly minor fixes and cleanups for the DW DMA driver. A
couple of them affect the DT binding so these may need to be updated to
maintain compatibility. The rest should be relatively straight-forward.

Changes since v1:
- zeroing struct dw_dma_slave before use
- fall back to old data_width property if data-width is not found
- append tags for few patches
- correct title of cover letter
- rebase on top of recent linux-next

Andy Shevchenko (11):
  dmaengine: dw: rename masters to reflect actual topology
  dmaengine: dw: substitute dma_read_byaddr by dma_readl_native
  dmaengine: dw: revisit data_width property
  dmaengine: dw: define counter variables as unsigned int
  dmaengine: dw: keep entire platform data in struct dw_dma
  dmaengine: dw: pass platform data via struct dw_dma_chip
  dmaengine: dw: platform: use field-by-field initialization
  dmaengine: dw: move dwc->paused to dwc->flags
  dmaengine: dw: move dwc->initialized to dwc->flags
  dmaengine: dw: move residue to a descriptor
  dmaengine: dw: set cdesc to NULL when free cyclic transfers

Mans Rullgard (4):
  dmaengine: dw: fix byte order of hw descriptor fields
  dmaengine: dw: clear LLP_[SD]_EN bits in last descriptor of a chain
  dmaengine: dw: set src and dst master select according to xfer
    direction
  dmaengine: dw: set LMS field in descriptors
