VDD1 and VDD2 are the core voltage regulators on OMAP3. VDD1 is used
to control MPU/IVA voltage, and VDD2 is used for CORE. These regulators
are needed by DVFS.
Voltage ranges for VDD1 and VDD2 are taken from twl4030/twl5030 data manuals:
- SWCS019L : TWL4030 ES3.1 Data Manual rev L
- SWCS030E : TWL5030 ES1.2 Data Manual rev E
