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 per charger. 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: v1 https://lists.linux-foundation.org/pipermail/linux-pm/2011-April/031052.html v2 https://lists.linux-foundation.org/pipermail/linux-pm/2011-April/031111.html v3 https://lists.linux-foundation.org/pipermail/linux-pm/2011-May/031267.html v4 https://lists.linux-foundation.org/pipermail/linux-pm/2011-May/031357.html v5 (last, applied) https://lists.linux-foundation.org/pipermail/linux-pm/2011-June/031561.html To see the usage example, please refer to: http://git.infradead.org/users/kmpark/linux-2.6-samsung/shortlog/refs/heads/charger-manager In this git branch, a test code for Exynos4-NURI is shown.
