Subject: [Query]usb: dwc2: suspend/resume support for DWC2_POWER_DOWN_PARAM_NONE case
Date: Tue, 16 Jun 2020 17:03:11 +0800	[thread overview]
Message-ID: <20200616164712.67bf105c@xhacker.debian> (raw)

Hi,

After reading current dwc2 code, I got an impression that resume from suspend
to ram isn't supported for DWC2_POWER_DOWN_PARAM_NONE case, right? In fact
we do see usb device can't resume properly with DWC2_POWER_DOWN_PARAM_NONE case.

If the impression is true, what's the proper technical direction? Add 
dwc2_host_enter_suspend() as dwc2_host_enter_hibernation()
and 
dwc2_host_exit_suspend() as dwc2_host_exit_hibernation()?

Thanks in advance,
Jisheng
