The DWC3 core on the Exynos8855 is instantiated with the generic DWC3 platform driver using a flattened model, where the controller is directly addressable without a separate glue layer. This is the first Samsung Exynos binding using the flattened representation and this series adds the device tree binding and platform driver support for this configuration. The binding follows qcom,snps-dwc3 pattern, a single node referencing snps,dwc3-common.yaml for shared DWC3 properties, with per-SoC constraints enforced via if-then conditionals. The MAINTAINERS entry is updated first so that the new binding falls under the existing ARM/Samsung SoC maintainership. Changes in v2: - Commit 2/3: Clarify this is the first Samsung Exynos binding using the flattened node representation. - Commit 3/3: Add the compatible entry in alphabetical order in the of_match_table. - Link to v1: https://lore.kernel.org/all/20260903071250.3421499-1-selvarasu.g@samsung.com/ Selvarasu Ganesan (3): MAINTAINERS: add Samsung USB DT binding to ARM/SAMSUNG entry dt-bindings: usb: Introduce samsung,snps-dwc3 usb: dwc3: Add Exynos8855 to the generic platform driver .../bindings/usb/samsung,snps-dwc3.yaml | 98 +++++++++++++++++++ MAINTAINERS | 1 + drivers/usb/dwc3/dwc3-generic-plat.c | 5 +- 3 files changed, 102 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/usb/samsung,snps-dwc3.yaml -- 2.17.1
