+* NXP LPC32xx Main Interrupt Controller
+ (MIC, including SIC1 and SIC2 secondary controllers)
+
+Required properties:
+- compatible: Should be "nxp,lpc3220-mic"
+- interrupt-controller: Identifies the node as an interrupt controller.
+- interrupt-parent: Empty for the interrupt controller itself
+- #interrupt-cells: The number of cells to define the interrupts. Should be 2.
+ The first cell is the IRQ number
+ The second cell is used to specify mode:
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+ Default for internal sources should be set to 4 (active high).
+- reg: Should contain MIC registers location and length
+
+Examples:
+ /*
+ * MIC
+ */
