   4 Subject: [PATCH] ARM: sun5i: dt: Add sun5i-a1*-usb-vbus-reg dts include files
   5
   6 Almost all sun5i-a10s boards have a gpio controlled vbus for usb1 using gpio
   7 pin PB10 as in the reference design. This commit adds an include file for this,
   8 avoiding the need to copy and paste the dts code.
   9
  10 For sun5i-a13 based board the reference design uses a gpio on the pmic, which
  11 we don't support yet. Still for consistency with all the other dts files also
  12 add a sun5i-a13-usb-vbus-reg.dtsi files, without a gpio reference for now.
