+* Arcx Anybus-S host
+
+This host communicates with the SoC over a parallel bus. It is
+expected that its Device Tree node is specified as the child of a node
+corresponding to the parallel bus used for communication.
+
+Required properties:
+
+ - compatible : The following string:
+ "arcx,anybuss-host"
+
+ - reg : bus memory area where the Anybus-S host dpram is located.
+
+ - interrupts : interrupt connected to the Anybus-S host interrupt line.
+ Generic interrupt client node bindings are described in
+ interrupt-controller/interrupts.txt
+
+ - resets : the reset line associated with the Anybus-S host.
+
+Example of usage:
+
+This example places the Anybus-S host on top of the i.MX WEIM parallel bus,
see:
+Documentation/devicetree/bindings/bus/imx-weim.txt
+
+&weim {
+ anybus-host@0 {
+ compatible = "arcx,anybuss-host";
+ reg = <0 0x400000 0x800>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <1 IRQ_TYPE_LEVEL_LOW>;
+ resets = <&anybus_bridge 0>;
+ /* fsl,weim-cs-timing is a i.MX WEIM bus specific property */
+ fsl,weim-cs-timing = <0x024400b1 0x00001010 0x20081100
+ 0x00000000 0xa0000240 0x00000000>;
