Hi,\

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.
