This Soc has 2 types HS phys. one in combo phy and another stand-alone. please refer the block diagrams in cover-letter.
1. samsung,exynosautov920-usbdrd-phy => represents hs phy (synopsys phy version-303) and it is same as "samsung,exynos850-usbdrd-phy". used same naming conventions
2. samsung,exynosautov920-usbdrd-hsphy => represents 'Add-on' HS phy(synopsys phy version-400) with SS phy in combo phy. this is different from "samsung,exynosautov920-usbdrd-phy" (reg offsets and bits are different).
samsung,exynosautov920-usb31drd-ssphy => represents SS phy in combo phy
