Subject: [PATCH v6 0/4] Fixes / cleanups in dw_dmac (affects on few subsystems)

This patch series (v3: http://www.spinics.net/lists/kernel/msg2215303.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 (old format is still supported though). The rest should
be relatively straight-forward.

This version has been tested on the following bare metal platforms:
- ATNGW100 (avr32 based platform) with dmatest
- Sam460ex (powerpc 44x based platform) with SATA
- Intel Braswell with UART
- Intel Galileo (Intel Quark based platform) with UART

(SATA driver and Intel Galileo UART support are based on this series and just
 published recently for a review)

Vinod, there are few patch sets developed on top of this one, so, the idea is
to keep this in an immuutable branch / tag.

Changes since v5:
- fixed an issue found by kbuildbot

Changes since v4:
- send proper set of patches
- add changelog

Changes since v3:
- add patch 1 to check value of dma-masters property
- drop the upstreamed patches
- update patch 2 to keep an array for data-width property as well

Changes since v2:
- add patch 1 to fix master selection which was broken for long time
- remove "use field-by-field initialization" patch since like Mans metioned in
  has mostly no value and even might increase error prone
- rebase on top of recent linux-next
- wide testing on several platforms

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 (4):
  dmaengine: dw: platform: check nr_masters to be non-zero
  dmaengine: dw: revisit data_width property
  dmaengine: dw: keep entire platform data in struct dw_dma
  dmaengine: dw: pass platform data via struct dw_dma_chip
