1. Add OTG PET device to TPL. OTG device shall support this device for allowing compliance automated testing. 2. Add otg_srp_reqd filed to gadget. OTG B-device shall enable this flag when OTG PET (Protocol and Electrical Tester) that acts as A-device sends Set Feature TEST_MODE with wIndex high byte value = 0x06. OTG PET expects B-device to initiate SRP after the end of current session. 3. Add otg_vbus_off to usb_bus. USB core enables this flag when OTG PET enumerates with bcdDevice[0] field in its Device Descriptor is equal to 1. OTG PET expects A-device to turn off the VBUS with in 5 sec of its disconnection which allows it to initiate SRP. 3. Add support to identify OTG PET and start HNP quickly.
