If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

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.
