6	The Synopsys designware mobile storage host controller is used to interface
7	a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
8	differences between the core Synopsys dw mshc controller properties described
9	by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific
10	extensions to the Synopsys Designware Mobile Storage Host Controller.
11	
12	Required Properties:
13	
14	* compatible: should be one of the following.
15	  - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extensions.

17	Example:
