+* Xtensa Interrupt Distributor and Programmable Interrupt Controller (MX)
+
+Required properties:
+- compatible: Should be "cdns,xtensa-mx".
+
+Remaining properties have exact same meaning as in Xtensa PIC
+(see cdns,xtensa-pic.txt).
+
+Examples:
+       pic: pic {
+               compatible = "cdns,xtensa-mx";
+               /* one cell: internal irq number,
+                * two cells: second cell == 0: internal irq number
+                *            second cell == 1: external irq number
+                */
+               #interrupt-cells = <2>;
+               interrupt-controller;
+       };
