According to the registers information document:
https://microchip-ung.github.io/lan9662_reginfo/reginfo_LAN9662.html?select=cpu,intr

The interrupt controller is mapped at offset 0x48 (offset in number of
32bit words).
-> Address offset: 0x48 * 4 = 0x120
-> size: (0x63 + 1) * 4 = 0x190

IMHO, the reg property value looks correct.

Best regards,
Hervé
