+NXP LPC32xx Wakeup Controller
+
+Required properties:
+- compatible: should be "nxp,lpc3220-wakeup"
+- reg: should contain wakeup controller registers location and length
+- #wakeup-cells: must be 2, the first cell describes wakeup source on
+ the controller, the second cell is a hardware interrupt number on IC.
+
+Examples:
+
+ /* System Control Block */
+ scb {
+ compatible = "simple-bus";
+ ranges = <0x0 0x040004000 0x00001000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ wakeup_int: wakeup-controller@20 {
+ compatible = "nxp,lpc3220-wakeup";
+ reg = <0x20 0x10>;
+ #wakeup-cells = <2>;
+ };
+
+ wakeup_pin: wakeup-controller@30 {
+ compatible = "nxp,lpc3220-wakeup";
+ reg = <0x30 0x10>;
+ #wakeup-cells = <2>;
+ };
+ };
+
+ /* Main Interrupt Controller */
+ mic: interrupt-controller@40008000 {
+ compatible = "nxp,lpc3220-mic";
+ reg = <0x40008000 0x4000>;
+ interrupt-controller;
+ interrupt-controller-name = "mic";
+ #interrupt-cells = <2>;
+
+ wakeup-sources = <&wakeup_int 7 29>,
+ <&wakeup_int 25 27>;
+ };
