[PATCH 3/8] usb: dwc3: exynos: Add support for Exynos850 variant

From: Sam Protsenko
Date: Fri Aug 18 2023 - 23:19:07 EST


Add Exynos850 compatible string and associated driver data. Only two
clocks are needed for this SoC:
- bus_early: bus clock needed for registers access
- ref: USB 2.0 DRD reference clock (50 MHz)
