Subject: [PATCH RESEND v2 2/6] dt-bindings: watchdog: Convert Allwinner watchdog to a schema
Date: Wed, 21 Aug 2019 16:38:31 +0200 [thread overview]
Message-ID: <20190821143835.7294-2-mripard@kernel.org> (raw)
In-Reply-To: <20190821143835.7294-1-mripard@kernel.org>
From: Maxime Ripard <maxime.ripard@bootlin.com>
The Allwinner SoCs have a watchdog supported in Linux, with a matching
Device Tree binding.
Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.
Reviewed-by: Rob Herring <robh@kernel.org>

Changes from v1:
- Use generic watchdog schema
- Use unevaluatedProperties instead of additionalProperties
