Currently the duration check on the discharging duration setting is checking the charging duration rather than the discharging duration due to a cut-n-paste coding error. Fix this by checking the value desc->charging_max_duration_ms.

Commit 395a7251 (power: supply: sbs-battery: don't assume i2c errors as battery disconnect) overwrites the original error code returned from internal functions. On such a sporadic i2c error, a user will get a wrong value without errors. Fixes: 395a7251 (power: supply: sbs-battery: don't assume i2c errors as battery disconnect) Signed-off-by:

The Maxim ModelGauge family supports fine-tuning by setting a compensation value (named rcomp in the docs). The value is affected by battery chemistry and ambient temperature. Add support for reading maxim,rcomp from DT and configuring the device with the supplied value. Temperature adjustment is not implemented at the moment, because there is no provision for receiving the ambient temperature at the moment. Signed-off-by:

The max17040 fuel gauge is part of a family of 8 chips that have very similar mode of operations and registers. This change adds: - compatible strings for all supported devices and handling for the minor differences between them; - handling for devices reporting double capacity via maxim,double-soc; The datasheets of the supported devices are linked [0] [1] [2] [3].

Maxim max17040 is a fuel gauge from a larger family utilising the Model Gauge technology. Document all different compatible strings that the max17040 driver recognizes. Some devices in the wild report double the capacity. The maxim,double-soc (from State-Of-Charge) property fixes that. Examples: https://lore.kernel.org/patchwork/patch/1263411/#1468420Signed-off-by:

Two actions were performed during remove - power supply dereg and delayed work cleanup. Power supply dereg can be handled by using the devm_ version of the registration function. Work cleanup can be added as a devm_action. If probe fails after psy registration it will now be cleaned up properly. Signed-off-by:

Currently the sign for CURRENT_NOW and CURRENT_AVG is a bit of a mess. There are basically 3 different ways battery fuel gauges report the current: 1. uses negative values for discharging and positive values for charging 2. uses positive values for discharging and negative values for discharging (opposit of 1) 3. only uses positive values As a result userspace currently cannot use the sign at all in a generic way. Let's solve the issue by documenting a canonical way for reporting the data and ensure new drivers follow this way. Then existing drivers can be fixed on a case-by-case basis. The 'negative value = battery discharging' has been choosen, since there are only very few drivers doing it the other way around. Signed-off-by:

bq27000, bq27010 and upcoming bq34z100 have a Capacity Inaccurate flag. However except this similarity, bq34z100 is quite different than bq27000/bq27010, so flag BQ27XXX_O_ZERO cannot be reused here.

Commit 6f24ff97 ("power: supply: bq27xxx_battery: Add the BQ27Z561 Battery monitor") and commit d74534c2 ("power: bq27xxx_battery: Add support for additional bq27xxx family devices") added support for new device types by copying most of the code and adding necessary quirks. However they did not copy the code in bq27xxx_battery_status() responsible for returning POWER_SUPPLY_STATUS_NOT_CHARGING. Unify the bq27xxx_battery_status() so for all types when charger is supplied, it will return "not charging" status. Signed-off-by:

Some fault events like the over-current condition will get resolved by the hardware, by e.g. disabling the port. As the status in the interrupt status register is cleared on read when the fault is resolved, the sysfs health property will only contain the correct health status for the first time it is read after such an event, even if the actual fault condition (like a VBUS short) still persists. To reflect this properly in the property we cache the last health status and only update the cache when a actual change happens, i.e. the ERR bit in the status register flips, as this one properly reflects a continued fault condition. The ALERT pin however, is not driven by the ERR status, but by the actual fault status, so the pin will change back to it's default state when the hardware has automatically resolved the fault by cutting the power. Thus we never get an IRQ when the actual fault condition has been resolved and the ERR status bit has been cleared in auto-recovery mode. To get this information we need to poll the interrupt status register after some time to see if the fault is gone and update our cache in that case. To avoid any additional locking, we handle both paths (IRQ firing and delayed polling) through the same single-threaded delayed work. Signed-off-by:
