In the existing Exynos series, EINT control register enumerated after a specific offset (e.g EXYNOS_GPIO_ECON_OFFSET). However, in ExynosAutov920 SoC, the register that controls EINT belongs to each GPIO group, and each GPIO group has 0x1000 align. This is a structure to protect the GPIO group with S2MPU in VM environment, and will only be applied in ExynosAuto series SoCs.
