[PATCH v2 1/2] dt-bindings: power: reset: gpio-poweroff: Add 'timeout_ms' property

From: Moritz Fischer
Date: Mon Feb 19 2018 - 18:04:36 EST


Add 'timeout_ms' property to support boards where the 3s timeout that the
current driver defaults to is too short.

Changes from v1:
- Addressed Rob's feedback (timeout -> timeout_ms)
- Added to old example rather than creating separate one
