Fix LTC4412 false reporting #2

Closed ReallySmall closed 9 years ago

LTC4412 stat line should be high when battery is the power source and low when wall adapter is the power source. However it remains high at all times. Appears to be a hardware issue.

Turned out to be a combination of using too strong a pull-up value and not disabling the mcp23017 pin pullup.
