Subject: [PATCH v5 5/6] dt-bindings: phy: samsung,usb3-drd-phy: add
ExynosAutov920 combo ssphy
This phy supports USB3.1 SSP+(10Gbps) protocol and is backwards
compatible to the USB3.0 SS(5Gbps). It requires two clocks, named
"phy" and "ref". The required supplies for USB3.1 are named as
vdd075_usb30(0.75v), vdd18_usb30(1.8v).
Add schemas for combo ssphy found on this SoC.
