Hi, This is a follow-up of Macpaul Lin's previous patchset to resolve usb gadget driver work with OTG 2.0, main changes: 1. keep one usb_otg_descriptor definition and introduce a kernel config to identify the OTG release version, if OTG 2.0 or later, add bcdOTG. 2. Override the usb_otg_descriptor defined by gadget driver if HW has its own config in new gadget options, otherwise keep all unchanged. 3. OTG features(SRP/HNP/ADP) can be decided by usb HW properties and USB driver config. 4. Change the chipidea usb driver to use the updated mechanism.
