Subject: [PATCH v2 2/2] dt-bindings: media: Convert Allwinner A10 IR to a schema
From: Maxime Ripard <maxime.ripard@...tlin.com>
The older Allwinner SoCs have a IR receiver 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.
