14 SiFive (and other RISC-V) SOCs include an implementation of the SiFive
15 Core Local Interruptor (CLINT) for M-mode timer and M-mode inter-processor
16 interrupts. It directly connects to the timer and inter-processor interrupt
17 lines of various HARTs (or CPUs) so RISC-V per-HART (or per-CPU) local
18 interrupt controller is the parent interrupt controller for CLINT device.
19 The clock frequency of CLINT is specified via "timebase-frequency" DT
20 property of "/cpus" DT node. The "timebase-frequency" DT property is
23 T-Head C906/C910 CPU cores include an implementation of CLINT too, however
24 their implementation lacks a memory-mapped MTIME register, thus not
