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. Signed-off-by: Selvarasu Ganesan --- Changes in v3: - Drop the MAINTAINERS patch. - Drop the samsung,snps-dwc3 generic fallback compatible. The binding now uses the SoC specific compatible samsung,exynos8855-dwc3 only. - Binding file is renamed to match the compatible string. - Remove the "select" from the binding. - List the clocks (ref, bus) explicitly and drop the redundant if/then block. - Update the driver patch to use the new compatible string. - Drop the v2 Reviewed-by (Alim Akhtar) and Acked-by (Thinh Nguyen) tags as the patches changed. re-requesting them. - Link to v2: https://lore.kernel.org/all/20260916122229.2604003-1-selvarasu.g@samsung.com/ 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 (2): dt-bindings: usb: Add Samsung Exynos8855 DWC3 controller binding usb: dwc3: Add Exynos8855 to the generic platform driver .../bindings/usb/samsung,exynos8855-dwc3.yaml | 74 +++++++++++++++++++ drivers/usb/dwc3/dwc3-generic-plat.c | 5 +- 2 files changed, 77 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/usb/samsung,exynos8855-dwc3.yaml -- 2.17.1
