This patch set enables and initialises DWMMC for Exynos5250 on SMDK5250. Adds driver changes required for DWMMC. Adds FDT support for DWMMC. Adds EMMC boot support for SMDK5250.
This patch set is based on: "EXYNOS: mmc: support DesignWare Controller for Samsung-SoC", which is merged in u-boot-mmc. "Exynos: clock: support get_mmc_clk for exynos". "Add DT based ethernet driver for SMDK5250". "SMDK5250: Add FDT support" present at the following link http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/149991
Changes from V1: 1)Corrected in response to review comments. 2)Created separate board files for FDT and non-FDT versions. 3)Added binding file for DWMMC device node. 4)Removed the propname 'index' from device node. 5)Prefixed the vendor name 'samsung' before propname in device node. 6)Ensured to have same signature for the function exynos_dwmci_init() for both FDT and non-FDT versions. 7)EMMC clock setting has been moved from spl_boot.c to clock_init.c.
Changes from V2: 1)Updation of commit message and resubmition of proper patch set.
