 * Devicetree for the Samsung Galaxy Ace 2 GT-I8160 also known as Codina.
 *
 * NOTE: this is the most common variant according to the vendor tree, known

 * AB8505 and other changes. There is also talk about some variants having a
 * Samsung S6D27A1 display, indicated by passing a different command line from
 * the boot loader.
 *
 * The Samsung tree further talks about GT-I8160P and GT-I8160chn (China).
 * The GT-I8160 plain is known as the "europe" variant.
 * The GT-I8160P is the CDMA version and it appears to not use the ST
 * Microelectronics accelerometer and reportedly has NFC mounted.
 * The GT-I8160chn appears to be the same as the europe variant.
 *
 * There is also the Codina-TMO, Samsung SGH-T599, which has its own device
