It is interfaced to host controller using I2C interface. The battery fuel gauge uses a separate I2C bus. properties: compatible: const: richtek,rt5033 reg: maxItems: 1 interrupts: maxItems: 1 regulators: 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.
