Subject: [PATCH 1/2] power_supply: Add support for CHARGE_CONTROL_* attributes
Date: Tue, 9 Oct 2012 22:25:29 +0530 [thread overview]
Message-ID: <1349801729-19604-1-git-send-email-ramakrishna.pallala@intel.com> (raw)
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.
