iam using i.mx6sl platform in my custom board. jelly bean/ kitkat (using 3.0 kernel). i have to sense the battery voltage whether its charging or how many percent remaining. (like a tablet). It should inform about shut down .
Regarding this I am using tsc2004 touch controller and i connected aux pin to battery BQ24103(bat pin).
right now its showing as charged whether adapter is connected or not.
i look into that file /kernel/driver/power/sabresd_battery.c in that there is function (max11801_read_adc) so it called max11801 driver file.
how can i port to my i.mx6sl platform.
