The WM831x PMICs provide power path management from three sources: a wall supply, USB and a battery with integrated charger. They also provide an additional backup supply with integrated for maintaining always on functionality such as the RTC and monitoring of power switches. After some initial configuration at startup the device operates autonomously, the driver simply provides reporting of the current state.

On the device we're currently developing, battery sizes of ~2.8Ah and current flow of ~600mA are typical. With that values, the life_sec computation overflows due to the multiplication by 3600.

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.

This adds a function that indicates that a battery is fully charged. It also includes functions to get a power_supply device from the class of registered devices by name reference. These can be used to find a specific battery to call power_supply_set_battery_charged() on. Some battery drivers might need this information to calibrate themselves.

When connecting a ds2760 to a partly loaded battery the first time, there must be a way to bootstrap the current_accum value. Without that, the current capactity value is bogus until the battery is fully charged for the first time.

In systems where the battery monitor is not part of the battery pack and is hence not bootstrapped with sane values, the full_active_uAh is likely to be zero. Handle that case by defaulting to the rated_capacity information which can be passed to the driver using the new module parameter.

For systems where the ds2760 is soldered directly on the PCB, the 'rated capacity' register is not set to anything useful. In order to allow users to bootstrap this value, introduce a new module parameter 'rated_capacity' and use it to write the internal EEPROM in case the value differes from what's been given.

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.

This patch allows machines to use an OTG transceiver driver instead of supplying a custom is_usb_online callback to check USB power. Also, in the case that the OTG transceiver handles charger control when connected to USB, a regulator named "ac_draw" can be supplied instead of the custom set_charge callback to control the charger when connected to AC. The check for (transceiver->state == OTG_STATE_B_PERIPHERAL) in otg_is_usb_online is probably too simple, I'm just using this with a peripheral only device and gpio_vbus + bq24022. I'm not sure which other OTG states can supply power. Signed-off-by: NPhilipp Zabel <philipp.zabel@gmail.com> Signed-off-by: NAnton Vorontsov <cbouatmailru@gmail.com>

The battery charger state machine switches into charging mode when the battery voltage falls below 96% of a battery float voltage. But 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 80%. This work_struct function restarts charging at regular intervals to make sure the battery doesn't discharge too much.

This patch adds support for the PMU provided by the WM8350 which implements battery, line and USB supplies including a battery charger. The hardware functions largely autonomously, with minimal software control required to initiate fast charging. Support for configuration of the USB supply is not yet implemented. This means that the hardware will remain in the mode configured at startup, by default limiting the current drawn from USB to 100mA.
