From a85b59c14d4082abcf27f63994e900dd00b5e572 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 1 Jun 2015 20:08:59 +0200 Subject: [PATCH] ARM: dts: sun8i: Enable USB DRC on Ippo Q8H-A23 tablets Enable the otg controller on Ippo Q8H tablets, 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.
