Grazvydas Ignotas wrote: After 270968c0984ae "bq27x00_battery: Fix reporting status value for bq27500 battery" status doesn't seem to be reported correctly when the battery is close to fully charged state. It reports "Not charging" while in fact there is >130mA current flowing to the battery according to current_now. This status report seems to be based on CHG bit in status register, but looking at the datasheet the description says "(Fast) charging allowed", which I guess means that the chip recommends charging and not that charging is actually going on? If you check the bit while battery is discharging and it's not full, the bit is also set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no power class device is found in power_supply_is_system_supplied(), the function currently returns 0, which basically means that the system is supposed to be running on battery. In practice, mobile devices tend to always implement at least one power class device and more often two (battery and AC adapter). Systems with no registered power class devices are more likely to be desktop systems, where the system is always powered by mains. So, change the default return value of power_supply_is_system_supplied() from 0 (running on battery) to 1 (running on mains.)

There are presently three possible values: Unknown - unknown power topology System - the power supply powers the whole system Device - it powers a specific device, or tree of devices A power supply which doesn't have a "scope" attribute should be assumed to have "System" scope.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because battery health monitoring should be done even when suspended, it needs to wake up and suspend periodically. Thus, userspace battery monitoring may incur too much overhead; every device and task is woken up periodically. Charger Manager uses suspend-again to provide in-suspend monitoring. This patch allows to monitor battery health in-suspend state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt for ac on/off can be missed during boot time. Check if online by seeing if we have power. We choose 0.5V since this is high enough to avoid random reading from a input that could be floating if no charger.
