Will drivers/usb/phy be removed? Is it not allowed to add new drivers? In our application, driver/phy is not suitable. We need to notify the phy driver when the USB hub port status changes. However, generic PHY drivers are designed for various device's PHY. And it seems inappropriate to add this function. So we choose to use driver/usb/phy. Thanks, Stanley
