[PATCH v2 01/22] usb: add OTG version number in usb_otg_descriptor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




From: Macpaul Lin <macpaul@xxxxxxxxx>

OTG 2.0 introduces bcdOTG to identify the OTG and EH supplement release
number with which the OTG device is compliant, so adds it for
usb_otg_descriptor.
