[RFCv2 6/9] dt-bindings: phy: meson-g12a-usb2-phy: convert to yaml

From: Neil Armstrong <hidden>
Date: 2019-08-05 12:03:17
Also in: linux-amlogic, linux-devicetree
Subsystem: arm/amlogic meson soc support, generic phy framework, open firmware and flattened device tree bindings, the rest · Maintainers: Neil Armstrong, Kevin Hilman, Vinod Koul, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

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.
