[PATCH v2 3/3] usb: dwc3: Add Exynos8855 to the generic platform driver

From: Selvarasu Ganesan

Date: Wed Sep 16 2026 - 08:30:47 EST


Add the "samsung,snps-dwc3" compatible string to dwc3-generic-plat so
the Exynos8855 USB3 DWC3 controller can probe through the generic DWC3
platform glue. While at it, alphabetically reorder the existing entries.

The "samsung,snps-dwc3" string is used as a generic fallback to support
any Exynos SoC that utilizes a flattened model instantiation. This
fallback allows multiple Exynos SoCs to be supported by the generic
platform driver simply by adding the fallback compatible to their
respective device tree nodes.
