> It seems however that newer ARMv8 Exynos SoC like Exynos850 and

> 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.
