Older Samsung Exynos SoC pin controller nodes (Exynos3250, Exynos4, Exynos5, Exynos5433) with external wake-up interrupts, expected to have one interrupt for multiplexing these wake-up interrupts. Also they expected to have exactly one pin controller capable of external wake-up interrupts. It seems however that newer ARMv8 Exynos SoC like Exynos850 and ExynosAutov9 have differences: 1. No multiplexed external wake-up interrupt, only direct, 2. More than one pin controller capable of external wake-up interrupts. Use dedicated ExynosAutov9 compatible for its external wake-up interrupts controller to indicate the differences.
