Charger Manager provides in-kernel battery charger management that
requires temperature monitoring during both normal and suspend-to-RAM states
and where each battery may have multiple chargers attached and the userland
wants to look at the aggregated information of the multiple chargers.
Charger Manager is a platform_driver with power-supply-class entries.
An instance of Charger Manager (a platform-device created with
Charger-Manager) represents a battery with chargers. If there are multiple
batteries with their own chargers acting independently in a system,
the system may need multiple instances of Charger Manager.
Multiple chargers (e.g., USB, wireless, and solar panels) may be included
as pairs of a regulator and a power-supply-class
Charger Manager glues multiple charger-related frameworks (regulators of
chargers, power-supply-class from chargers and fuel-gauge, RTC,
suspend-again, ...) together to provide aggregated information and
transparent battery monitoring to userspace.
For the discussions about the need for in-suspend monitoring, please
refer to the discussions of suspend-again in PM:
v5 (last, applied) https://lists.linux-foundation.org/pipermail/linux-pm/201...
To see the usage example, please refer to:
In this git branch, a test code for Exynos4-NURI is shown.
This patch set supports initial Charger Manager driver.
Changes for v3:
- rename variables and functions
- clean up code
- add build dependency of RTC_CLASS and REGULATOR
Changes for v2:
- change symbol type of Kconfig to boolean
