SubjectRe: [PATCH v2 4/5] USB: dwc2: Don't turn off the usbphy in suspend if wakeup is enabled
Douglas Anderson <> writes:

> If the 'snps,need-phy-for-wake' is set in the device tree then:
> - We know that we can wakeup, so call device_set_wakeup_capable().
> The USB core will use this knowledge to enable wakeup by default.
> - We know that we should keep the PHY on during suspend if something
> on our root hub needs remote wakeup. This requires the patch (USB:
> Export usb_wakeup_enabled_descendants()). Note that we don't keep
> the PHY on at suspend time if it's not needed because it would be a
> power draw.
> If we later find some users of dwc2 that can support wakeup without
> keeping the PHY on we may want to add a way to call
> device_set_wakeup_capable() without keeping the PHY on at suspend
