7 title: RISC-V Advanced Platform Level Interrupt Controller (APLIC)
14 platform level interrupt controller (APLIC) for handling wired interrupts
18 The RISC-V APLIC is implemented as hierarchical APLIC domains where all
19 interrupt sources connect to the root APLIC domain and a parent APLIC
20 domain can delegate interrupt sources to it's child APLIC domains. There
21 is one device tree node for each APLIC domain.
30 - qemu,aplic
31 - const: riscv,aplic
45 Given APLIC domain directly injects external interrupts to a set of
