From 361a4069727b1f43583314470e877e1187b35505 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 31 Jul 2015 14:53:38 +0200 Subject: [PATCH] ARM: dts: sun8i: Enable USB DRC on Ippo Q8H-A33 tablet Enable the otg/drc usb controller on the Ippo Q8H-A33 tablet, for now it is enabled in host-only mode, because true OTG support requires support for detecting and enabling Vbus through the axp221 pmic. For this to work the Vbus on the port must be enabled by u-boot, or a powered hub must be used.
