TWM (Traditional watch mode) is a low power mode supported on the BG platform. PMIC is configured differently while entering into TWM mode. Add a sysfs node to - 1. Allow the BG daemon to enable/disable TWM mode. echo 1 > /sys/class/pmic_twm/twm_enable --> Enable TWM mode echo 0 > /sys/class/pmic_twm/twm_enable --> Clear TWM mode 2. Allow the BG daemon to check the TWM_EXIT state. cat /sys/class/pmic_twm/twm_exit Value of "1" indicates exit from TWM state Also, add a notifier to notify other modules of the TWM enable configuration.
