'enum' is equivalent to 'oneOf' with a list of 'const' entries, but 'enum' is more concise and yields better error messages.

This interrupt controller is found in the Loongson-3 family of chips and
|
|
Loongson-2K1000 chip, as the primary package interrupt controller which
|
|
can route local I/O interrupt to interrupt lines of cores.

This property points how the children interrupts will be mapped into CPU

interrupt lines. Each cell refers to a parent interrupt line from 0 to 3
|
|
and each bit in the cell refers to a child interrupt from 0 to 31.
|
|
If a CPU interrupt line didn't connect with liointc, then keep its
|
|
cell with zero.
