Subject: [v3,2/2] usb: dwc3: pci: Intel Merrifield can be host
Date: Thu, 26 Jul 2018 14:48:57 +0300 [thread overview]
Message-ID: <20180726114857.86036-2-andriy.shevchenko@linux.intel.com> (raw)
On Intel Edison board the OTG function is enabled, thus,
USB can switch to the host mode.
Allow that by changing dr_mode property to "otg" for Intel Merrifield.
