| 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 | }; |
