When we merged the Gemini interrupt controller it was not yet discovered that this IP block is actually a standard Faraday Technology interrupt controller. As the IP block will probably appear in other designs as well, let's augment the DT bindings to reflect that it is first and foremost a standard Faraday part with a function name (FTINTC010) so that people reusing the IP easily find the driver they need. Sorry for the mistakes due to lack of information.

* Faraday Technologt FTINTC010 interrupt controller
|
|
|
|
This interrupt controller is a stock IP block from Faraday Technology found
|
|
in the Gemini SoCs and other designs.
|
|
|
|
Required properties:
|
|
- compatible: must be one of
|
|
"faraday,ftintc010"
|
|
"cortina,gemini-interrupt-controller" (deprecated)
|
|
- reg: The register bank for the interrupt controller.
|
|
- interrupt-controller: Identifies the node as an interrupt controller
|
|
- #interrupt-cells: The number of cells to define the interrupts.
|
|
Must be 2 as the controller can specify level or rising edge
|
|
IRQs. The bindings follows the standard binding for controllers
|
|
with two cells specified in
|
|
interrupt-controller/interrupts.txt
|
|
|
|
Example:
|
|
|
|
interrupt-controller@48000000 {
|
|
compatible = "faraday,ftintc010"
|
|
reg = <0x48000000 0x1000>;
|
|
interrupt-controller;
|
|
#interrupt-cells = <2>;
|
|
};
