[PATCH RFC 3/8] dt-bindings: soc: samsung: exynos-pmu: add samsung,pmu-intr-gen phandle

[Alexey Klimov]

Some Exynos-based SoCs, for instance Exynos850, require access
to the pmu interrupt generation register region which is exposed
as a syscon. Update the exynos-pmu bindings documentation to
reflect this.
