The legacy binding was limited to a PSP-centric view of the interrupt architecture and cannot describe interrupt routing and protection for the full AST2700 system. It is superseded by the new ASPEED AST2700 INTC0/INTC1 binding, which describes the interrupt controllers at the block-function level. There are no known upstream users of the removed binding.
