Subject: [PATCH v5 0/7] DMA: shdma: switch DT to use OF device ID tables

In this version of shdma Device Tree support I preserved the DT 
configuration approach via OF device ID tables from v4, but now it is only 
used for the DT-mode, the C-version is left untouched. In this series I 
only include one platform: r8a73a4-based APE6EVM, if accepted, others can 
be added easily. I also took care not to include mach/*.h headers in 
driver .c files. To illustrate the use of DT DMA support for MMC DMA on 
APE6EVM a patch from a previously separate patch series "DMA for MMCIF and 
SDHI devices in DT mode"
http://thread.gmane.org/gmane.linux.ports.sh.devel/25445
is now also included in this series.

This series should be applied on top of my previous shdma patches 
"DMA: shdma: fix CHCLR register address calculation"
https://lkml.org/lkml/2013/7/2/331
"DMA: shdma: several stylistic improvements and support for new SoCs"
http://thread.gmane.org/gmane.linux.ports.sh.devel/24826
"DMA: shdma: make a pointer const"
http://marc.info/?l=linux-sh&m=137545309332395&w=2

The above dependencies also mean, that the ARM patches shall only be 
applied after the DMA patches are upstream.

Guennadi Liakhovetski (7):
  DMA: shdma: switch DT mode to use configuration data from a match
    table
  DMA: shdma: remove private and unused defines from a global header
  DMA: shdma: add a header with common for ARM SoCs defines
  DMA: shdma: add r8a73a4 DMAC data to the device ID table
  ARM: shmobile: r8a73a4: add a DMAC platform device and clock for it
  ARM: shmobile: r8a73a4: add a DT node and a clock alias for the DMAC
  ARM: shmobile: ape6evm-reference: enable DMA for the MMC interface
