Subject[PATCH 2/5] dt-bindings: watchdog: Convert Allwinner watchdog to a schema
Date
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.
