[PATCH 0/3] Add USB DWC3 support for Samsung Exynos8855

[Selvarasu Ganesan]

The Samsung Exynos8855 SoC implements a Synopsys DesignWare USB3 DRD
controller. 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 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.
