Krzysztof Kozlowski 1755e227c2 dt-bindings: pinctrl: samsung: describe Exynos850 and ExynosAutov9 wake-ups
Older Samsung Exynos SoCs  (Exynos3250, Exynos4, Exynos5, Exynos5433)
expected pin controller node with external wake-up interrupts to have
one interrupt for multiplexing these wake-up interrupts.  Also they
expected to have exactly one such pin controller (capable of external
wake-up interrupts).

It seems however that newer ARMv8 Exynos SoCs like Exynos850 and
ExynosAutov9 have differences of their pin controllers 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.

This is a part of device tree bindings for Samsung S3C/S5P/Exynos SoC pin
controller.
External wake-up interrupts for Samsung S3C/S5P/Exynos SoC pin controller.
For S3C24xx, S3C64xx, S5PV210 and Exynos4210 compatible wake-up interrupt
controllers, only one pin-controller device node can include external wake-up
interrupts child node (in other words, only one External wake-up interrupts
pin-controller is supported).
For newer controllers, multiple pin-controller device node can include
external wake-up interrupts child node.
See also Documentation/devicetree/bindings/pinctrl/samsung,pinctrl.yaml for
additional information and example.
