+* Atmel High Speed MultiMedia Card Interface
+
+This controller on atmel products provides an interface for MMC, SD and SDIO
+types of memory cards.
+
+This file documents differences between the core properties described
+by mmc.txt and the properties used by the atmel-mci driver.
+
+1) MCI node
+
+Required properties:
+- compatible: should be "atmel,hsmci"
+- #address-cells: should be one. The cell is the slot id.
+- #size-cells: should be zero.
+- at least one slot node
+
+The node contains child nodes for each slot that the platform uses
+
+Example MCI node:
+
+mmc0: mmc at f0008000 {
+	compatible = "atmel,hsmci";
+	reg = <0xf0008000 0x600>;
+	interrupts = <12 4>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	[ child node definitions...]
+};
+
+2) slot nodes
+
+Required properties:
+- reg: should contain the slot id.
+- bus-width: number of data lines connected to the controller
+
+Optional properties:
+- cd-gpios: specify GPIOs for card detection
+- cd-inverted: invert the value of external card detect gpio line
+- wp-gpios: specify GPIOs for write protection
+
+Example slot node:
+
+slot at 0 {
+	reg = <0>;
+	bus-width = <4>;
+	cd-gpios = <&pioD 15 0>
+	cd-inverted;
+};
+
+Example full MCI node:
+mmc0: mmc at f0008000 {
+	compatible = "atmel,hsmci";
+	reg = <0xf0008000 0x600>;
+	interrupts = <12 4>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+	slot at 0 {
+		reg = <0>;
+		bus-width = <4>;
+		cd-gpios = <&pioD 15 0>
+		cd-inverted;
+	};
+	slot at 1 {
+		reg = <1>;
+		bus-width = <4>;
+	};
+};
