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 Hi3798CV200
10specific extensions to the Synopsys Designware Mobile Storage Host Controller.

12Required Properties:
13- compatible: Should contain "hisilicon,hi3798cv200-dw-mshc".
14- clocks: A list of phandle + clock-specifier pairs for the clocks listed
15  in clock-names.
16- clock-names: Should contain the following:
17	"ciu" - The ciu clock described in synopsys-dw-mshc.txt.
18	"biu" - The biu clock described in synopsys-dw-mshc.txt.
19	"ciu-sample" - Hi3798CV200 extended phase clock for ciu sampling.
20	"ciu-drive"  - Hi3798CV200 extended phase clock for ciu driving.
