Hi, > So,do you mean that I should rename the C source file as phy-rockchip-usb2.c > ? what I mean is that you can simply rename the kconfig entry to PHY_ROCKCHIP_USB. If you explain that it is for usb 2.0 in the description (as it is already the case), it is enough, no needs to put USB2 in the kconfig entry name :) Have a nice evening, Romain -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
