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. It is meant to be an architecture dependent function to support advanced power management. Since PMIC framework uses lists internally to link different devices, its initialization must be done just after malloc initialization.
Please consider commits from this patch set as the example of advanced power management for a particular HW (Trats board in this case).
In the new approach PMICs are selected with their names (e.g. 'pmic dump MAX8997_PMIC') Presented patch set is a first step to change 'pmic' command to more generic (i.e. power) to provide control for multiple devices.
Moreover device's battery is treated as an oridinary "power" device (like PMIC). Due to that, framework unification is possible. For even more versalite design, each power device instance can specify its parent.
For trats one can build a following scheme (it can de different for other boards): ----------------- --------| BAT |------------ | | | | | ----------------- | | | | |/ |/ |/
|FG | |MUIC | |CHRG | | | | | | |
Finally, this patch series also comprises of a "namespace" cleanup - an attempt to rename "pmic" to "power" to better reflect generality of this framework.
Test HW:
