+* ZTE specific extensions to the Synopsys Designware Mobile Storage
+  Host Controller
+
+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 ZTE specific
+extensions to the Synopsys Designware Mobile Storage Host Controller.
+
+Required Properties:
+
+* compatible: should be
+	- "zx,dw-mshc": for ZX SoCs
+
+Example:
+
+	mmc1: mmc@1110000 {
+		compatible = "zte,dw-mshc";
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reg = <0x01110000 0x1000>;
+		interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>;
+		fifo-depth = <32>;
+		fifo-addr = <0x200>;
+		fifo-watermark-quirk;
+		bus-width = <4>;
+		clock-frequency = <50000000>;
+		clocks = <&topcrm SD0_AHB>, <&topcrm SD0_WCLK>;
+		clock-names = "biu", "ciu";
+		num-slots = <1>;
+		max-frequency = <50000000>;
+		cap-sdio-irq;
+		cap-sd-highspeed;
