Kernel-4.18.0-80.el8_bfticu

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>;
};
