+* ARM Nested Vector Interrupt Controller (NVIC)
+
+The NVIC provides an interrupt controller that is tightly coupled to
+Cortex-M based processor cores. The NVIC implemented on different SoCs
+vary in the number of interrupts and priority bits per interrupt.
+
+Main node required properties:
+
+- compatible : should be one of:
+ "arm,v6m-nvic"
+ "arm,v7m-nvic"
+ "arm,v8m-nvic"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ The 1st cell contains the interrupt number for the interrupt type.
+
+ The 2nd cell is the priority of the interrupt.
+
+- reg : Specifies base physical address(s) and size of the NVIC registers.
+ This is at a fixed address (0xe000e100) and size (0xc00).
+
+- arm,num-irq-priority-bits: The number of priority bits implemented by the
+ given SoC
+
+Example:
+
+ intc: interrupt-controller@e000e100 {
+ compatible = "arm,v7m-nvic";
+ #interrupt-cells = <2>;
+ #address-cells = <1>;
+ interrupt-controller;
+ reg = <0xe000e100 0xc00>;
+ arm,num-irq-priority-bits = <4>;
+ };
