description:
RT5033 is a multifunction device which includes battery charger, fuel gauge,
flash LED current source, LDO and synchronous Buck converter for portable
applications. It is interfaced to host controller using I2C interface. The
battery fuel gauge uses a separate I2C bus.

description:
The regulators of RT5033 have to be instantiated under a sub-node named
"regulators". For SAFE_LDO voltage there is only one value of 4.9 V. LDO
voltage ranges from 1.2 V to 3.0 V in 0.1 V steps. BUCK voltage ranges
from 1.0 V to 3.0 V in 0.1 V steps.
