[PATCH v4 0/2] 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 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.

- List the clocks (ref, bus) explicitly and drop the redundant if/then
  block.
