+ST-Ericsson U300 Device Tree Bindings
+
+For various board the "board" node may contain specific properties
+that pertain to this particular board, such as board-specific GPIOs
+or board power regulator supplies.
+
+Required root node property:
+
+compatible="stericsson,u300";
+
+Required node: syscon
+This contains the system controller.
+- compatible: must be "stericsson,u300-syscon".
+- reg: the base address and size of the system controller.
+
+Boards with the U300 SoC include:
+
+S365 "Small Board U365":
+
+Required node: s365
+This contains the board-specific information.
+- compatible: must be "stericsson,s365".
+- vana15-supply: the regulator supplying the 1.5V to drive the
+  board.
+- syscon: a pointer to the syscon node so we can access the
+  syscon registers to set the board as self-powered.
+
+Example:
+
+/ {
+	model = "ST-Ericsson U300";
+	compatible = "stericsson,u300";
+	#address-cells = <1>;
+	#size-cells = <1>;
+
+	s365 {
+		compatible = "stericsson,s365";
+		vana15-supply = <&ab3100_ldo_d_reg>;
+		syscon = <&syscon>;
+	};
+
+	syscon: syscon@c0011000 {
+		compatible = "stericsson,u300-syscon";
+		reg = <0xc0011000 0x1000>;
+	};
+};
