+* Imagination 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 Imagination specific
+extensions to the Synopsys Designware Mobile Storage Host Controller.
+
+Required Properties:
+
+* compatible: should be
+	- "img,pistachio-dw-mshc": for Pistachio SoCs
+
+Example:
+
+	mmc@18142000 {
+		compatible = "img,pistachio-dw-mshc";
+		reg = <0x18142000 0x400>;
+		interrupts = <GIC_SHARED 39 IRQ_TYPE_LEVEL_HIGH>;
+
+		clocks = <&system_clk>, <&sdhost_clk>;
+		clock-names = "biu", "ciu";
+
+		fifo-depth = <0x20>;
+		bus-width = <4>;
+		num-slots = <1>;
+		disable-wp;
+	};
