0006 *
0007 * This phone is closely related to the Codina, but has:
0008 * - No CPU speed cap, full ~1GHz rate
0009 * - Different power management IC, AB8505
0010 * - As AB8505 has a micro USB phy, no TI TSU6111
0011 * - Different power routing such as the removal of the external LDO for the
0012 * touchscreen in favor of using the AB8505
0013 * - Using a regulator for the key backlight LED
0014 * - Using the Samsung S6D27A1 panel by default
0015 * - The panel is using one of the ordinary AB8505 regulators for 1.8V
0016 * - WiFi/Bluetooth combi chip upgraded to BCM4334
0017 * - GPIO for backlight control moved from 68 to 69
