- KEYMILE bfticu Chassis Management FPGA
- The bfticu is a multifunction device that manages the whole chassis.
- Its main functionality is to collect IRQs from the whole chassis and signals
- them to a single controller.
- Required properties:
- - compatible: "keymile,bfticu"
- - interrupt-controller: the bfticu FPGA is an interrupt controller
- - interrupts: the main IRQ line to signal the collected IRQs
- - #interrupt-cells : is 2 and their usage is compliant to the 2 cells variant
- of Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
- - interrupt-parent: the parent IRQ ctrl the main IRQ is connected to
- - reg: access on the parent local bus (chip select, offset in chip select, size)
- Example:
- chassis-mgmt@3,0 {
- compatible = "keymile,bfticu";
- interrupt-controller;
- #interrupt-cells = <2>;
- reg = <3 0 0x100>;
- interrupt-parent = <&mpic>;
- interrupts = <6 1 0 0>;
- };
