From 23c091d95a9860b5afb245fee7c20931ab1dce28 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 1 Nov 2019 15:32:16 +0100 Subject: [PATCH] dt-bindings: usb: Convert Allwinner A10 mUSB controller to a schema The Allwinner SoCs have an mUSB controller that 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.
