From: Jens Wiklander <[email protected]> Sync Linux kernel dwc3 changes from v4.14 to v4.15. The following files are preserved across the import: Makefile Kconfig dwc3-meson-g12a.c dwc3-meson-gxl.c dwc3-omap.c dwc3-uniphier.c dwc3-generic.h dwc3-generic.c dwc3-generic-sti.c dwc3-layerscape.c ti_usb_phy.c Skipping unused files: debugfs.c drd.c dwc3-exynos.c dwc3-haps.c dwc3-imx8mp.c dwc3-keystone.c dwc3-octeon.c dwc3-of-simple.c dwc3-pci.c dwc3-qcom.c dwc3-qcom-legacy.c dwc3-rtk.c dwc3-st.c dwc3-xilinx.c host.c trace.c trace.h ulpi.c Note that this is a raw import and doesn't build. A fixup commit at the end of the series fixes that.
