I am currently running a system with an i.MX6 Solo X and a PF 200 power manager component. I am also running Linux.
I want to read the current voltage of the coin cell from the power manager device (LICELL pin).
but no luck. I realize there is the i2c control for the coin cell however I don't want to set the voltage but only read the current voltage coming out of the battery via the power manager.
If there is a way to read on linux via sysfs that would be best. I know of the regulator devices in /sys/class/regulators but I'm not sure which one would be the for the external lithium ion battery (LICELL).
