[PATCH v3 00/15] Fixes / cleanups in dw_dmac (affects on few subsystems)

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

This patch series (v2: http://www.spinics.net/lists/dmaengine/msg08274.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.

This version has been tested on the following bare metal platforms:
- ATNGW100 (avr32 based platform) with MMC
- 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 not
 available in upstream yet)

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 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 (11):
  dmaengine: dw: fix master selection
  dmaengine: dw: rename masters to reflect actual topology
  dmaengine: dw: substitute dma_read_byaddr by dma_readl_native
  dmaengine: dw: revisit data_width property
