 12description:
 13  RT5033 is a multifunction device which includes battery charger, fuel gauge,
 14  flash LED current source, LDO and synchronous Buck converter for portable
 15  applications. It is interfaced to host controller using I2C interface. The
 16  battery fuel gauge uses a separate I2C bus.

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