29- interrupt-controller : Identifies the node as an interrupt controller
30- #interrupt-cells : Use the same format as specified by GIC in arm,gic.txt.
31- reg: Physical base address of the intpol registers and length of memory
32  mapped region. Could be multiple bases here. Ex: mt6797 needs 2 reg, others
33  need 1.
