Subject: [PATCH v2 25/28] dt-bindings: pinctrl: samsung: describe Exynos850 and ExynosAutov9 wake-ups
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 of their pin controller node capable of
external wake-up interrupts:
1. No multiplexed external wake-up interrupt, only direct,
2. More than one pin controller capable of external wake-up interrupts.
Add dedicated Exynos850 and ExynosAutov9 compatibles.
