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- 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 16Example: 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 }; 26
