Sol led: Handle power supply states
Handle power-supply states for Charging/Discharging Set blink/solid Led settings as below LED Brighness depend on Device Charging State ---------------------------------------------- -- Full while Device Charging -- Half Brighness while not Charging Led Functional Mode Depend on the Battery capacity -------------------------------------------------- Battery Level < LOW_CAP_THRESHOLD_DEFAULT -- Fast Blink "charging_low" led node(s) LOW_CAP_THRESHOLD_DEFAULT < Battery Level < BATT_CAP_THRESHOLD_HIGH -- Slow Blink "charging" led node(s) (If device charging) -- Enable Solid 50% brightness for "charging" led node(s) (If device not charging) BATT_CAP_THRESHOLD_HIGH < Battery Level < BATT_CAP_THRESHOLD_FULL -- Slow Blink "charging_full" led node(s) (If device charging) -- Enable Solid 50% brightness for "charging_full" led node(s) (If device not charging) Battery Level == BATT_CAP_THRESHOLD_FULL -- Enable Solid 100% brightness for "charging_full" led node(s) Change-Id: I0abf35ea5ee51ade808ac196d8e56d7dcac33d9c Signed-off-by: Srihari Sathyanarayana <sriharis@motorola.com> Signed-off-by: Vijayakumar Gn <vijaygn@motorola.com> Reviewed-on: https://gerrit.mot.com/2516362 SME-Granted: SME Approvals Granted SLTApproved: Slta Waiver Tested-by: Jira Key Reviewed-by: Perry White <awhite6@motorola.com> Reviewed-by: Qing Chang <qing@motorola.com> Submit-Approved: Jira Key
