Is sharing a PHY IP block or driver ever possible for any HW? yes it is possible, and OMAP5 shares the same IP for USB3 and SATA. PHYs don't know about USB, SATA, Ethernet and whatnot. PHYs know solely about the physical layer. Their work is just to generate the proper electrical signals. > Hence, I don't think removing "USB" from the filename makes sense, nor > even moving it into a generic PHY directory. fair enough, I have now renamed tegra to phy-tegra-usb.c -- balbi
