From mboxrd@z Thu Jan 1 00:00:00 1970 From: mamlinav@gmail.com (Aleksei Mamlin) Date: Thu, 24 Sep 2015 10:33:46 +0300 Subject: [PATCH] ARM: dts: sun4i: Enable USB DRC on the Marsboard A10 Message-ID: <1443080026-4011-1-git-send-email-mamlinav@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Enable the otg/drc usb controller on the Marsboard A10. Similar to Cubieboard, the 5V of the otg is directly connected to the general 5V, so we only use the id pin.
