+description: |
+ Silicon Mitus SM5703 is a multi-function device, that consists of several
+ modules, designed for a mobile phone use. It consists of
+ LDO, Buck, USBLDO and VBUS regulators, a flash LED driver, a MUIC unit,
+ a fuel gauge and a battery charger circuit. The MUIC and Fuel-Gauge units
+ are separate from the main MFD, having their own i2c lines, while the
+ LED driver, regulators and charger are sharing the main i2c bus of the MFD.
