18c2ecf20Sopenharmony_ci* ASPEED AST2400 and AST2500 coprocessor interrupt controller 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciThis file describes the bindings for the interrupt controller present 48c2ecf20Sopenharmony_ciin the AST2400 and AST2500 BMC SoCs which provides interrupt to the 58c2ecf20Sopenharmony_ciColdFire coprocessor. 68c2ecf20Sopenharmony_ci 78c2ecf20Sopenharmony_ciIt is not a normal interrupt controller and it would be rather 88c2ecf20Sopenharmony_ciinconvenient to create an interrupt tree for it as it somewhat shares 98c2ecf20Sopenharmony_cisome of the same sources as the main ARM interrupt controller but with 108c2ecf20Sopenharmony_cidifferent numbers. 118c2ecf20Sopenharmony_ci 128c2ecf20Sopenharmony_ciThe AST2500 supports a SW generated interrupt 138c2ecf20Sopenharmony_ci 148c2ecf20Sopenharmony_ciRequired properties: 158c2ecf20Sopenharmony_ci- reg: address and length of the register for the device. 168c2ecf20Sopenharmony_ci- compatible: "aspeed,cvic" and one of: 178c2ecf20Sopenharmony_ci "aspeed,ast2400-cvic" 188c2ecf20Sopenharmony_ci or 198c2ecf20Sopenharmony_ci "aspeed,ast2500-cvic" 208c2ecf20Sopenharmony_ci 218c2ecf20Sopenharmony_ci- valid-sources: One cell, bitmap of supported sources for the implementation 228c2ecf20Sopenharmony_ci 238c2ecf20Sopenharmony_ciOptional properties; 248c2ecf20Sopenharmony_ci- copro-sw-interrupts: List of interrupt numbers that can be used as 258c2ecf20Sopenharmony_ci SW interrupts from the ARM to the coprocessor. 268c2ecf20Sopenharmony_ci (AST2500 only) 278c2ecf20Sopenharmony_ci 288c2ecf20Sopenharmony_ciExample: 298c2ecf20Sopenharmony_ci 308c2ecf20Sopenharmony_ci cvic: copro-interrupt-controller@1e6c2000 { 318c2ecf20Sopenharmony_ci compatible = "aspeed,ast2500-cvic"; 328c2ecf20Sopenharmony_ci valid-sources = <0xffffffff>; 338c2ecf20Sopenharmony_ci copro-sw-interrupts = <1>; 348c2ecf20Sopenharmony_ci reg = <0x1e6c2000 0x80>; 358c2ecf20Sopenharmony_ci }; 36
