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