did you have a look at arnd and anton comments regarding 'supplied-to' and boolean property
Try to keep your comments inline, situated below the relevant comment.
ab8500_battery_info: ab8500_bat_type {
battery-type = <2>;
thermistor-on-batctrl = <1>;
You have this as a bool here, and ...
e.g:
ab8500_battery_info: ab8500_bat_type {
thermistor-on-batctrl;
... a standard property here. I suggest you drop the bool value.
I'm guessing it's just the documentation that needs amending.
