   3  * Devicetree for the Samsung Galaxy Ace 2 GT-I8160 also known as Codina.
   4  *
   5  * NOTE: this is the most common variant according to the vendor tree, known
   6  * as "R0.0". There appears to be a "R0.4" variant with backlight on GPIO69,
   7  * AB8505 and other changes. There is also talk about some variants having a
   8  * Samsung S6D27A1 display, indicated by passing a different command line from
   9  * the boot loader.
  10  *
  11  * The Samsung tree further talks about GT-I8160P and GT-I8160chn (China).
  12  * The GT-I8160 plain is known as the "europe" variant.
  13  * The GT-I8160P is the CDMA version and it appears to not use the ST
  14  * Microelectronics accelerometer and reportedly has NFC mounted.
  15  * The GT-I8160chn appears to be the same as the europe variant.
  16  *
  17  * There is also the Codina-TMO, Samsung SGH-T599, which has its own device
  18  * tree.
