-* Exynos 5250 DWC_mobile_storage
-
-The Exynos 5250 provides DWC_mobile_storage interface which supports
-. Embedded Multimedia Cards (EMMC-version 4.5)
-. Secure Digital memory (SD mem-version 2.0)
-. Secure Digital I/O (SDIO-version 3.0)
-. Consumer Electronics Advanced Transport Architecture (CE-ATA-version 1.1)
-
-The Exynos 5250 DWC_mobile_storage provides four channels.
-SOC specific and Board specific properties are channel specific.
-
-Required SoC Specific Properties:
-
-- compatible: should be
-	- samsung,exynos5250-dwmmc: for exynos5250 platforms
-
-- reg: physical base address of the controller and length of memory mapped
-	region.
-
-- interrupts: The interrupt number to the cpu.
-
-Required Board Specific Properties:
-
-- #address-cells: should be 1.
-- #size-cells: should be 0.
-- samsung,bus-width: The width of the bus used to interface the devices
-	supported by DWC_mobile_storage (SD-MMC/EMMC/SDIO).
-	. Typically the bus width is 4 or 8.
-- samsung,timing: The timing values to be written into the
-	Drv/sample clock selection register of corresponding channel.
-	. It is comprised of 3 values corresponding to the 3 fileds
-	  'SelClk_sample', 'SelClk_drv' and 'DIVRATIO' of CLKSEL register.
-	. SelClk_sample: Select sample clock among 8 shifted clocks.
-	. SelClk_drv: Select drv clock among 8 shifted clocks.
-	. DIVRATIO: Clock Divide ratio select.
-	. The above 3 values are used by the clock phase shifter.
-
-Example:
-
-mmc@12200000 {
-	samsung,bus-width = <8>;
-	samsung,timing = <1 3 3>;
-	samsung,removable = <1>;
-}
-In the above example,
-	. The bus width is 8
-	. Timing is comprised of 3 values as explained below
-		1 - SelClk_sample
-		3 - SelClk_drv
-		3 - DIVRATIO
-	. The 'removable' flag indicates whether the the particilar device
-	  cannot be removed (always present) or it is a removable device.
-		1 - Indicates that the device is removable.
-		0 - Indicates that the device cannot be removed.
