6The Synopsys designware mobile storage host controller is used to interface
7a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
8differences between the core Synopsys dw mshc controller properties described
9by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific
10extensions to the Synopsys Designware Mobile Storage Host Controller.

12Required Properties:
13
14* compatible: should be one of the following.
15  - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extensions.
