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 - reg: access on the parent local bus (chip select, offset in chip select, size)
14
15 Example:
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 };
