Please refer to
Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.txt
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt source. Must be a single cell with a value of at least 3.
If the system requires describing PPI affinity, then the value must
be at least 4.
