Subject: [PATCH v8 1/6] dt-bindings: phy: samsung,usb3-drd-phy: add
 ExynosAutov920 HS phy compatible

Document support for the USB20 phy found on the ExynosAutov920 SoC. The
USB20 phy is functionally identical to that on the Exynos850 SoC, so no
driver changes are needed to support this phy. However, add a dedicated
compatible string for USB20 phy found in this SoC.
