Subject: [PATCH v4 3/4] dt-bindings: mmc: dw-mshc-hi3798cv200: convert to
 YAML

From: Yang Xiwen <forbidden405@...look.com>

convert the legacy txt binding to modern YAML and rename to
hisilicon,hi3798cv200-dw-mshc.yaml. No semantic change.

-* 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.
-
-Example:
-
-	emmc: mmc@...0000 {
-		compatible = "hisilicon,hi3798cv200-dw-mshc";
-		reg = <0x9830000 0x10000>;
-		interrupts = <GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&crg HISTB_MMC_CIU_CLK>,
-			 <&crg HISTB_MMC_BIU_CLK>,
-			 <&crg HISTB_MMC_SAMPLE_CLK>,
-			 <&crg HISTB_MMC_DRV_CLK>;
-		clock-names = "ciu", "biu", "ciu-sample", "ciu-drive";
-		fifo-depth = <256>;
-		clock-frequency = <200000000>;
-		cap-mmc-highspeed;
-		mmc-ddr-1_8v;
-		mmc-hs200-1_8v;
-		non-removable;
-		bus-width = <8>;
