Subject: [PATCH RESEND v2 2/6] dt-bindings: watchdog: Convert Allwinner watchdog to a schema
Date: Wed, 21 Aug 2019 16:38:31 +0200
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>
Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>

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