Hi Stefano, Tom, Any thoughts or ideas for this patch series?
> PMIC framework has been redesigned to support multiple instances of > power related devices (e.g. fuel gauge, PMICs, chargers, micro USB > IC, battery). > > Due to that, code at other architectures and boards have been > adjusted properly. > > New power_init_board() method at ./lib/board.c file has been > introduced.
