Subject: [PATCH 4/5] dt-bindings: sound: Convert Allwinner A23 analog codec to a schema
Date: Tue, 27 Aug 2019 16:25:46 +0200 [thread overview]
Message-ID: <20190827142547.14577-4-mripard@kernel.org> (raw)
In-Reply-To: <20190827142547.14577-1-mripard@kernel.org>
From: Maxime Ripard <maxime.ripard@bootlin.com>
The Allwinner A23 SoC and later have an embedded audio codec that uses a
separate controller to drive its analog part, which is 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.
