Subject: [v2,3/3] dwc3: Intel Merrifield can be host
Date: Mon, 23 Jul 2018 16:12:40 +0300 [thread overview]
Message-ID: <20180723131240.67852-3-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.
