-* 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.
