[PATCH v4 0/9] mmc: dw_mmc: add support for device tree based instantiation

[Thomas Abraham]

This is the fourth version of the patch series that adds device tree support
for Synopsis Designware Mobile Storage Host Controller. In this version, the
significant change is the spliting of Exynos specific code into a seperate
file, as suggested by Seungwon Jeon <tgih.jun at samsung.com>. Spliting the
Exynos specific code into a seperate file did infact keeps the core driver
code clean, which otherwise was littered with Exynos specific code. I hope
the changes look sane, though. This has been tested only on smdk5250 board.

  mmc: dw_mmc: convert copy of struct device in struct dw_mci to a reference
