HPET (High Precision Event Timer) defines a new set of timers, which are used by the operating system to schedule threads, interrupt the kernel and interrupt the multimedia timer server. The operating system can assign different timers to different applications. By configuration, each timer can generate interrupt independently. The loongson2 HPET module includes a main count and three comparators , all of which are 32 bits wide. Among the three comparators, only one comparator supports periodic interrupt, all three comparators support non periodic interrupts.

Thanks for the contribution, but as HPET is a fairly common peripheral that have well standardized behavior, why not simply add DT support to the drivers/char/hpet.c and be done with it?
