It is interfaced to host controller using I2C interface. The16 battery fuel gauge uses a separate I2C bus.17 18properties:19 compatible:20 const: richtek,rt503321 22 reg:23 maxItems: 124 25 interrupts:26 maxItems: 127 28 regulators:29 description:30 The regulators of RT5033 have to be instantiated under a sub-node named31 "regulators". For SAFE_LDO voltage there is only one value of 4.9 V. LDO32 voltage ranges from 1.2 V to 3.0 V in 0.1 V steps.
