   4 Subject: [PATCH] ARM: sun4i: dt: Add sun4i-a10-usb-vbus-reg dts include file
   5
   6 Almost all sun4i and sun7i boards have a gpio controlled vbus for usb1 and
   7 usb2, using gpio pin PH6 and PH3 as in the reference design. This commit adds
   8 an include file for this, avoiding the need to copy and paste the exact same
   9 dts code to almost all sun4i and sun7i dts files.
