* usb: chipidea: core: add sysfs groupPeter Chen2017-04-141-0/+9
Sometimes, the user needs to adjust some properties for controllers, eg the role for controller, we add sysfs group for them. The attribute 'role' is used to switch host/gadget role dynamically, the uewr can read the current role, and write the other role compare to current one to finish the switch.
