1 * NXP LPC32xx Main Interrupt Controller
2 (MIC, including SIC1 and SIC2 secondary controllers)
5 - compatible: Should be "nxp,lpc3220-mic"
6 - interrupt-controller: Identifies the node as an interrupt controller.
7 - interrupt-parent: Empty for the interrupt controller itself
8 - #interrupt-cells: The number of cells to define the interrupts. Should be 2.
9 The first cell is the IRQ number
10 The second cell is used to specify mode:
11 1 = low-to-high edge triggered
12 2 = high-to-low edge triggered
13 4 = active high level-sensitive
14 8 = active low level-sensitive
15 Default for internal sources should be set to 4 (active high).
16 - reg: Should contain MIC registers location and length
22 mic: interrupt-controller@40008000 {
23 compatible = "nxp,lpc3220-mic";
26 #interrupt-cells = <2>;
27 reg = <0x40008000 0xC000>;
34 compatible = "nxp,lpc3220-adc";
35 reg = <0x40048000 0x1000>;
36 interrupt-parent = <&mic>;
