* pmu_battery: Fix battery full reportingThomas Champagne2009-12-17
| | | | | | | | | | | Prior to this patch, pmu_battery was unable to report battery full status. This patch fixes the issue by adding a proper handling code into pmu_bat_get_property(): if we're on AC and the battery isn't charging, then the battery is considered full.

| * power_supply_sysfs: Handle -ENODATA in a special wayAnton Vorontsov2009-12-02
| | | | | | | | | | | | | | | | | | | | | | There are cases when some device can not report any meaningful value, e.g. TWL4030 charger can report voltage only when charging is active. In these cases drivers will return -ENODATA, and we shouldn't flood kernel log with error messages. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>

| * pcf50633: Query charger status directlyPaul Fertser2009-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Current scheme is fragile and is likely to go off sync, especially on batfull->adapter charging automatic MBC transition. Query the status bit every time we need it instead. We need to export another function to query for USB presence because we can't read anything from PCF50633 (via I2C) inside irq context and that is needed by usb gadgets.

| | | | | | | | | | | | | | | | | | | | | | | | If chgmod == BATFULL, setting chgena has no effect. Datasheet says we need to set resume instead but when autoresume is used resume doesn't work. Clear and set chgena instead. This enables a user to force charging by re-plugging USB even when the charger entered Battery Full mode, might be handy before a long trip.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | After reaching Battery Full condition MBC state machine switches back into charging mode when the battery voltage falls below 96% of a battery float voltage. The voltage drop in Li-Ion batteries is marginal (1-2%) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 75-80%. That is a desired behaviour recommended by battery manufacturers, don't mess with it. Signed-off-by: Paul Fertser <fercerpav@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>

It also gets set automatically every time usb current limit is changed. Limiting charging current also prevents violating USB specification in the case when the whole device is shut down and usb current limit is reset to the factory default by the pcf50633 state transition.

* | mfd: Mask and unmask wm8350 IRQs on request and freeMark Brown2009-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring the WM8350 IRQ API more in line with the generic IRQ API by masking and unmasking interrupts as they are requested and freed. This is mostly just a case of deleting the mask and unmask calls from the individual drivers. The RTC driver is changed to mask the periodic IRQ after requesting it rather than only unmasking the alarm IRQ. If the periodic IRQ fires in the period where it is reqested then there will be a spurious notification but there should be no serious consequences from this. The CODEC drive is changed to explicitly disable headphone jack detection prior to requesting the IRQs. This will avoid the IRQ firing with no jack set up.

| | | | | | | | | | | | | | | | | | | | | | | | | | Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ds2760's internal current meter is not reliable enough as it has an inacurracy of around ~15%. Without any correction for that error, the current accumulator is couting up all the time, even though the battery is already fully charged and hence destroys the static information. The longer it is connected, the worse is the aberration. Fortunately, this can be corrected by the DS2760_CURRENT_OFFSET_BIAS register. Using the external power_supply_set_battery_charged() function, this register is now gauging the measurement. A delayed work is used to debounce flaky GPIO signals and to let the current value settle. Also see Maxim's application note AN4188.

* da9030_battery: Fix race between event handler and monitorMike Rapoport2009-06-08
| | | | | | | | | | | | | | | | | | | There are cases when charging monitor and the event handler try to change the charger state simultaneously. For instance, a charger is connected to the system, there's the detection event and the event handler tries to enable charging. It is possible that the periodic charging monitor runs at the same time and it still thinks there's no external charger. So it tries to disable the charging. As the result, even if the conditions necessary to charge the battery hold, there will be no actual charging. The patch changes the event handler so that instead of enabling/ disabling the charger immediately it would rather make the monitor run. The monitor code then decides what should be the charger state.

|/ / | | | | | | | | | | | | | | | | | | ACPI has smart batteries, which work in units of energy and measure rate of (dis)charge as power, thus it is not appropriate to export it as a current_now. Current_now will still be exported to allow for userland applications to match. Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
