Subject: dwc3: gadget suspend/resume vs system suspend/resume
Date: Wed, 15 Feb 2023 11:40:15 +0200 [thread overview]
Message-ID: <7e28eb10-f27b-682a-dfb3-fec3e70b01f6@kernel.org> (raw)
Hi Thinh,
Currently dwc3 gadget disconnects from the bus in the system suspend path. i.e. dwc3_gadget_suspend()->dwc3_disconnect_gadget().
Is it reasonable to expect dwc3 gadget to do a USB suspend instead of a USB disconnect during system suspend?
At USB resume, system can wake up and resume and then dwc3 gadget can resume.
I'd like to know your opinion please if this is a reasonable expectation or something just not possible to achieve. Thanks!
cheers,
-roger
