Modern embedded platforms are most likely to embed a Power Management Integrated Circuit (PMIC). This component provides the different regulators to the board, controls which external power supply is used, recharges batteries, protects the board of over-voltage, etc.

Within the Linux kernel, such PMICs are typically handled via a combination of drivers in the IIO, MFD, power supply and regulator frameworks, and this talk proposes a walk-through how a PMIC is supported using these different subsystems.

To illustrate this presentation, the example of the X-Powers PMICs, which are frequently used in numerous Allwinner ARM platforms, will be used.
