[PATCH 1/2] power_supply: Add support for CHARGE_CONTROL_* attributes

From: Ramakrishna Pallala
Date: Tue Oct 09 2012 - 14:13:26 EST


Add support for power supply attributes CHARGE_CONTROL_LIMIT
and CHARGE_CONTROL_LIMIT_MAX.

These new attributes will enable the user space to implement
custom charging algorithms based on platform state.
