+ * 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
+ * as "R0.0". There appears to be a "R0.4" variant with backlight on GPIO69,
+ * 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
+ * tree.
