[PATCH 09/19] usb: dwc2: gadget: ignore pm suspend/resume in L2

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

 



From: Gregory Herrero <gregory.herrero@xxxxxxxxx>

Nothing to be done in pm suspend/resume when controller is in L2.
Don't disconnect or reset. State is already saved when putting
controller in hibernation and will be restored on USB bus resume.
