-* NXP LPC32xx MIC, SIC1 and SIC2 Interrupt Controllers
-
-Required properties:
-- compatible: "nxp,lpc3220-mic" or "nxp,lpc3220-sic".
-- reg: should contain IC registers location and length.
-- interrupt-controller: identifies the node as an interrupt controller.
-- #interrupt-cells: the number of cells to define an interrupt, should be 2.
-  The first cell is the IRQ number, the second cell is used to specify
-  one of the supported IRQ types:
-      IRQ_TYPE_EDGE_RISING = low-to-high edge triggered,
-      IRQ_TYPE_EDGE_FALLING = high-to-low edge triggered,
-      IRQ_TYPE_LEVEL_HIGH = active high level-sensitive,
-      IRQ_TYPE_LEVEL_LOW = active low level-sensitive.
-  Reset value is IRQ_TYPE_LEVEL_LOW.
-
-Optional properties:
-- interrupts: empty for MIC interrupt controller, cascaded MIC
-  hardware interrupts for SIC1 and SIC2
-
-Examples:
