Subject: [PATCH v3 1/2] dt-bindings: power: reset: gpio-poweroff: Add 'timeout-ms' property
Date: Thu, 22 Feb 2018 15:17:13 -0800 [thread overview]
Message-ID: <20180222231714.11843-1-mdf@kernel.org> (raw)
Add 'timeout-ms' property to support boards where the 3s timeout that the
current driver defaults to is too short.
Signed-off-by: Moritz Fischer <mdf@kernel.org>

Changes from v2:
- Addressed Rob's feedback (timeout_ms -> timeout-ms)
Changes from v1:
- Addressed Rob's feedback (timeout -> timeout_ms)
- Added to old example rather than creating separate one
