[PATCH 2/2] usb: chipidea: udc: do not run udc directly when start udc in otg fsm mode

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

 



From: Li Jun <b47624@xxxxxxxxxxxxx>

For A-device, when load gadget driver, we should not run udc either as this
will be controlled by otg fsm.
