+* Arcx anybus bridge
+
+This chip communicates with the SoC over the WEIM bus. It is
+expected that its Device Tree node is specified as the child of a node
+corresponding to the WEIM bus used for communication.
+
+Required properties:
+
+  - compatible : The following chip-specific string:
+        "arcx,anybus-bridge"
+
+  - reg :
+	weim memory area where the cpld registers are located,	followed by:
+	weim memory area of the first  anybus-s slot,		followed by:
+	weim memory area of the second anybus-s slot.
+
+  - enable-gpios : the gpio connected to the bridge's 'enable gpio'.
+
+  - pwms : the pwm connected to the bridge's 'pwm input'.
+
+  - irq-gpios : the gpios connected to the bridge's interrupt lines.
+	note that there is no need to provide the 'interrupts' property here.
+
+Example of usage:
+
+&weim {
+	bridge@0,0 {
+		compatible = "arcx,anybus-bridge";
+		reg = <0 0 0x100>, <0 0x400000 0x800>, <1 0x400000 0x800>;
+		fsl,weim-cs-timing = <0x024400b1 0x00001010 0x20081100
+				0x00000000 0xa0000240 0x00000000>;
+		enable-gpios = <&gpio5 2 GPIO_ACTIVE_HIGH>;
+		pwms = <&pwm3 0 571>;
+		irq-gpios = <&gpio1 1 GPIO_ACTIVE_HIGH>,
+					<&gpio1 5 GPIO_ACTIVE_HIGH>;
+	};
+};
