usb: dwc3: initialize platform data at pci glue layer (8f317b47) · Commits · 戴 / test

This patch initializes platform data at pci glue layer, and SoCs x86-based platform vendor is able to define their flags in platform data at bus glue layer. Then do some independent behaviors at dwc3 core level. Signed-off-by:
