1	KEYMILE bfticu Chassis Management FPGA
2	
3	The bfticu is a multifunction device that manages the whole chassis.
4	Its main functionality is to collect IRQs from the whole chassis and signals
5	them to a single controller.
6	
7	Required 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	- interrupt-parent: the parent IRQ ctrl the main IRQ is connected to
14	- reg: access on the parent local bus (chip select, offset in chip select, size)
15	
16	Example:
17	
18		chassis-mgmt@3,0 {
19			compatible = "keymile,bfticu";
20			interrupt-controller;
21			#interrupt-cells = <2>;
22			reg = <3 0 0x100>;
23			interrupt-parent = <&mpic>;
24			interrupts = <6 1 0 0>;
25		};
