1* ASPEED AST2400 and AST2500 coprocessor interrupt controller
2
3This file describes the bindings for the interrupt controller present
4in the AST2400 and AST2500 BMC SoCs which provides interrupt to the
5ColdFire coprocessor.
6
7It is not a normal interrupt controller and it would be rather
8inconvenient to create an interrupt tree for it as it somewhat shares
9some of the same sources as the main ARM interrupt controller but with
10different numbers.
11
12The AST2500 supports a SW generated interrupt
13
14Required properties:
15- reg: address and length of the register for the device.
16- compatible: "aspeed,cvic" and one of:
17		"aspeed,ast2400-cvic"
18	      or
19		"aspeed,ast2500-cvic"
20
21- valid-sources: One cell, bitmap of supported sources for the implementation
22
23Optional properties;
24- copro-sw-interrupts: List of interrupt numbers that can be used as
25		       SW interrupts from the ARM to the coprocessor.
26		       (AST2500 only)
27
28Example:
29
30	cvic: copro-interrupt-controller@1e6c2000 {
31		compatible = "aspeed,ast2500-cvic";
32		valid-sources = <0xffffffff>;
33		copro-sw-interrupts = <1>;
34		reg = <0x1e6c2000 0x80>;
35	};
