* ASPEED AST2400 and AST2500 coprocessor interrupt controller This file describes the bindings for the interrupt controller present in the AST2400 and AST2500 BMC SoCs which provides interrupt to the ColdFire coprocessor. It is not a normal interrupt controller and it would be rather inconvenient to create an interrupt tree for it as it somewhat shares some of the same sources as the main ARM interrupt controller but with different numbers. The AST2500 supports a SW generated interrupt Required properties: - reg: address and length of the register for the device. - compatible: "aspeed,cvic" and one of: "aspeed,ast2400-cvic" or "aspeed,ast2500-cvic" - valid-sources: One cell, bitmap of supported sources for the implementation Optional properties; - copro-sw-interrupts: List of interrupt numbers that can be used as SW interrupts from the ARM to the coprocessor. (AST2500 only) Example: cvic: copro-interrupt-controller@1e6c2000 { compatible = "aspeed,ast2500-cvic"; valid-sources = <0xffffffff>; copro-sw-interrupts = <1>; reg = <0x1e6c2000 0x80>; };
