I noticed that, instead of the usb-powerdomain i turned off the usb-powerdomain. Therefore this should probably be 'power_domain_off(&priv->pd_usb);'. However this should not make a difference in function. > > > ret = power_domain_get_by_name(dev, &priv->pd_usb_phy1, "usb-phy1"); > if (ret < 0) > -- > 2.25.1 >
