The TWL4030 aka TPS65950 has USB PHY, power managment and audio codec.
The USB PHY isn't used and is handled by the nxp1707a [1] See more information on USB
It seems to be documented - not under this part number - at TIs website
A quick check indicates the I2C bus addresses match - see 13.3 in above datasheet.
If this is the correct part, the following description applies:
The TPS65950 contains;
- Power management
- Several regulators - switched mode and LDO.
- Audio codec
- Five DACs, two ADCs
- Several power amplifiers.
- Microphone amplifiers
- USB tranciever
- Highspeed OTG compatible with integrated charge pump, and carkit support, designed for direct connection to the SoC.
- an ac/USB charger
- LED drivers
- ADC
- ADC can measure both input voltages to device, or voltages connected externally.
- RTC
- GPIO
- This can support switches, keypads, ...
