2020-05-15dt-bindings: phy: meson8b-usb2: Add compatible string for Meson8m2Martin Blumenstingl1-0/+1
The USB2 PHY on Meson8m2 is identical to the one on Meson8b but different to the one on Meson8. The only known difference is that Meson8 does not set the ACA_ENABLE bit while Meson8b and Meson8m2 do. Add an explicit compatible string for Meson8m2 so those differences can be taken care of.

2020-05-15dt-bindings: phy: meson8b-usb2: Convert to json-schemaMartin Blumenstingl1-0/+63
Now that we have the DT validation in place, let's convert the device tree bindings for the Amlogic Meson8, Meson8b, Meson8m2 and GXBB USB2 PHY over to a YAML schema. While here, also add the fallback compatible string "amlogic,meson-gxbb-usb2-phy" which is already used in arch/arm/boot/dts/meson{,8,8b}.dtsi.
