Subject: [PATCH 0/7] mmc: dw_mmc: add support for device tree based instantiation 

This patch series adds device tree support for Synopsis Designware Mobile
Storage Host Controller.

The first patch adds clock lookup in the driver and this is optional. Platforms
that do not need any clock gating and control for the dw_mmc controllers will
not be affected with this change. The second patch adds a quirk to notify the
controller about the absence of the write protect line.

The third patch adds device tree support and fourth patch adds Samsung
Exynos5250 specific controlller extentions to the driver. The rest of the
patches in the series enable support for dw_mmc support on the Samsing
Exynos5250 based platforms.

This patchset has been derived from Samsung internal patches prepared by
Abhilash Kesavan <a.kesavan@...sung.com>.
