* 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 */ mic: interrupt-controller@40008000 { compatible = "nxp,lpc3220-mic"; interrupt-controller; interrupt-parent; #interrupt-cells = <2>; reg = <0x40008000 0xC000>; }; /* * ADC */ adc@40048000 { compatible = "nxp,lpc3220-adc"; reg = <0x40048000 0x1000>; interrupt-parent = <&mic>; interrupts = <39 4>; };
