Roy Luo 381adb1243 Usb: Listen to USB sysfs attribute for device state ... Poll the sysfs attributes that represents usb device state in either of the following states: not attached, powered, default, addressed, configured. The information is useful in detecting non compliant USB cable, which will be supported in later patch sets. This patch lays the ground work to monitor the sysfs attributes in both device and host modes. The thread to poll uevent is re-used to poll sysfs because this serialize type-C port events and usb device state changes, hence prevent potential races. Added a thin abstration layer and a map to keep epoll data so that it's easier to dynamically add/delete files to epoll, which is needed for usb devices in host mode.
