+* Hisilicon Hi3798CV200 specific extensions to the Synopsys Designware Mobile
+ Storage Host Controller
+Read synopsys-dw-mshc.txt for more details
+The Synopsys designware mobile storage host controller is used to interface
+a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
+differences between the core Synopsys dw mshc controller properties described
+by synopsys-dw-mshc.txt and the properties used by the Hisilicon Hi3798CV200
+specific extensions to the Synopsys Designware Mobile Storage Host Controller.
+Required Properties:
+- compatible: Should contain "hisilicon,hi3798cv200-dw-mshc".
+- clocks: A list of phandle + clock-specifier pairs for the clocks listed
+ in clock-names.
+- clock-names: Should contain the following:
+ "ciu" - The ciu clock described in synopsys-dw-mshc.txt.
+ "biu" - The biu clock described in synopsys-dw-mshc.txt.
+ "ciu-sample" - Hi3798CV200 extended phase clock for ciu sampling.
+ "ciu-drive" - Hi3798CV200 extended phase clock for ciu driving.
