   7  * This phone is closely related to the Codina, but has:
   8  * - No CPU speed cap, full ~1GHz rate
   9  * - Different power management IC, AB8505
  10  * - As AB8505 has a micro USB phy, no TI TSU6111
  11  * - Different power routing such as the removal of the external LDO for the
  12  *   touchscreen in favor of using the AB8505
  13  * - Using a regulator for the key backlight LED
  14  * - Using the Samsung S6D27A1 panel by default
  15  * - The panel is using one of the ordinary AB8505 regulators for 1.8V
  16  * - WiFi/Bluetooth combi chip upgraded to BCM4334
  17  * - GPIO for backlight control moved from 68 to 69
