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 };
