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 |
|
- 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>; |
|
};
