From c3593cc95c240663bd9c191c1029237e467575af Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Fri, 7 Feb 2014 18:08:03 +0100
Subject: [PATCH] ARM: sun4i: dt: Add sun4i-a10-usb-vbus-reg dts include file
Almost all sun4i and sun7i boards have a gpio controlled vbus for usb1 and
usb2, using gpio pin PH6 and PH3 as in the reference design. This commit adds
an include file for this, avoiding the need to copy and paste the exact same
dts code to almost all sun4i and sun7i dts files.
