Subject: [PATCH 6/9] dt-bindings: phy: meson-g12a-usb2-phy: convert to yaml
Date: Thu, 8 Aug 2019 10:51:36 +0200 [thread overview]
Message-ID: <20190808085139.21438-7-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190808085139.21438-1-narmstrong@baylibre.com>
Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic G12A USB2 PHY over to a YAML schemas.
While the original phy bindings specifies phy-supply as required,
the examples and implementations makes it optional, thus phy-supply
is not in the required list of attributes.
