'loongson,parent_int_map' is an array, but the schema is defining a matrix resulting in the follow warnings: Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.example.dt.yaml: interrupt-controller@3ff01400: loongson,parent_int_map:0: [4043309055] is too short Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.example.dt.yaml: interrupt-controller@3ff01400: loongson,parent_int_map:1: [251658240] is too short Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.example.dt.yaml: interrupt-controller@3ff01400: loongson,parent_int_map:2: [0] is too short Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.example.dt.yaml: interrupt-controller@3ff01400: loongson,parent_int_map:3: [0] is too short The correct way to define an array is a list in 'items' and/or a size defined by 'minItems' and 'maxItems'.

This interrupt controller is found in the Loongson-3 family of chips 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 children interrupt fron 0 to 31.
|
|
If a CPU interrupt line didn't connected with liointc, then keep it's
|
|
cell with zero.
