Controls LEDs, various power supplies via an I²C connection to the PMIC.
Devices attached to I2C bus:
Two I²C buses are attached to the MCU. For one, the SoC is the master; for the other, the MCU is the master.
* UC (master?)
Devices attached to MCU master I²C bus:
* MCU (master)
* Fuel Gauge
* Accelerometer (slave address 0x18)
* Accelerometer (slave address 0x18)
* SoC (master? slave?)
* PMIC
* maybe more?
