* OMAP4: battery charger: Don't check battery presence in interrupt.Oleksandr Kozaruk2014-10-011-5/+0
| | | | | | | | | | | | | | | During the battery charging process interrupts can occur and software must read the reason of the interrupt. One of the reasons is battery removed/insert event, which is already analyzed in interrupt service routine. During AC removal, due to transient reading battery ID resistor may return low value and absence of battery could be falsely detected. Checking battery presence in ISR prevents reading the reason of interrupt, which should be done.

* OPMAP4: AC charger: AC power supply disconnect event.Oleksandr Kozaruk2014-10-011-0/+1
| | | | | | | | | | | | | If board is booted with AC power supply connected, then first disconnect event is not detected and /sys/class/power_supply/twl6030_ac/online returns '2' meaning AC charging. Now, charge state value detected when probe was called is saved in device info structure.

| | | | | | | | | | | | bq2415x has 32 second watchdog timer. If within 32 second the watchdog timer is not reset then the charge is terminated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The battery capacity reported may not always be representative of how much charge is actually remaining. When the battery is almost empty, the output voltage may dip and go below the threshold for safe operation. The "almost empty" watermark will be different for different designs so it needs to be passed through platform data. The battery reported capacity is thus scaled from [min,~100] to [0,100].
