   5  * NOTE: this is the most common variant according to the vendor tree, known

   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 knonw as the "europe" variant.
  13  * The GT-I8160P appears to not use the ST Microelectronics accelerometer.
  14  * The GT-I8160chn appears to be the same as the europe variant.
