> Remove hard-coded values for:
> - Fast Charge current,
> - End Of Charge current,
> - Fast Charge timer,
> - Overvoltage Protection Threshold,
> - Battery Constant Voltage,
> and use DTS to configure them. This allows using the max14577 charger
> driver with different batteries.
>
> Now the charger driver requires valid configuration data from DTS. In
> case of wrong configuration data it fails during probe. Patch adds
> of_compatible to the charger mfd cell in MFD driver core.

Too many chars. Didn't checkpatch.pl complain about this?
