1KEYMILE bfticu Chassis Management FPGA
2
3The bfticu is a multifunction device that manages the whole chassis.
4Its main functionality is to collect IRQs from the whole chassis and signals
5them to a single controller.
6
7Required properties:
8- compatible: "keymile,bfticu"
9- interrupt-controller: the bfticu FPGA is an interrupt controller
10- interrupts: the main IRQ line to signal the collected IRQs
11- #interrupt-cells : is 2 and their usage is compliant to the 2 cells variant
12  of Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
13- reg: access on the parent local bus (chip select, offset in chip select, size)
14
15Example:
16
17	chassis-mgmt@3,0 {
18		compatible = "keymile,bfticu";
19		interrupt-controller;
20		#interrupt-cells = <2>;
21		reg = <3 0 0x100>;
22		interrupt-parent = <&mpic>;
23		interrupts = <6 1 0 0>;
24	};
