   4 Subject: [PATCH] ARM: sunxi: dt: Add sunxi-common-regulators include file
   5
   6 Most sunxi boards with a sata connector also have a gpio controlled connector
   7 for sata target power and almost all sunxi boards have a gpio controlled vbus
   8 for usb1 and usb2.
   9
  10 This commit adds an include file for the regulators representing these
  11 supplies, avoiding the need to copy and paste the regulator code to allmost
  12 all sunxi board dts files.
