There is no support to measure the main charger voltage and current using AB9540 gpadc. Therefore this has been removed from the driver. Signed-off-by:

When the charging safety timer elapses, the battery health is shown as "Good". This is misleading and also makes it difficult to distinguish issues relating to discharging despite the fact that the charger is still connected. When in actual fact a safety timer elapse is an indication of a fault in the battery. Here we make this clearer by reporting POWER_SUPPLY_HEALTH_UNSPEC_FAILURE instead. Signed-off-by: -

The Linux Power Supply framework expects battery temperatures to have a resolution of 0.1 degree Celsius; however, the AB8500 btemp driver supplies a battery temperature resolution of 1 degree Celsius. We therefore have to use a factor 10 on the measured values. Signed-off-by:

Today the battery recharge is determined with a voltage threshold. This voltage threshold is only valid when the battery is relaxed. In charging algorithm the voltage read is the loaded battery voltage and no compensation is done to get the relaxed voltage. When maintenance charging is not selected, this makes the recharging condition to almost immediately activate when there is a discharge present on the battery. Depending on which vendor the battery comes from this behavior can wear out the battery much faster than normal. The fuelgauge driver is responsible to monitor the actual battery capacity and is able to estimate the remaining capacity. It is better to use the remaining capacity as a limit to determine when battery should be recharged. Signed-off-by:

Use 'platform_device' in kernel messages rather than i2c client device node. lp8788_update_charger_params() needs additional argument, 'pdev'. Then, remove unnecessary lp8788 private data in lp8788_irq_register(). Signed-off-by:

Kim, Milo authored
The lp8788-charger is a platform driver of lp8788-mfd. The platform device is allocated when mfd_add_devices() is called in lp8788-mfd. On the other hand, 'lp->dev' is the i2c client device. Therefore, this 'platform_device' is a proper parent device in case of resource managed mem alloc and device kernel message. Signed-off-by:

Some devices, Buffalo Linkstation LS-XHL and LS-CHLv2 for example, power-off by restarting to letting u-boot hold the SoC until the user presses a key. Add a generic driver to implement this. It binds a function to pm_power_off, which calls arm_pm_restart. Signed-off-by:

devm_kzalloc should not be followed by kfree, as this results in a double free. The problem was found using the following semantic match (http://coccinelle.lip6.fr/): // <smpl> @@ expression x,e; @@ x = devm_kzalloc(...) ... when != x = e ?-kfree(x,...); // </smpl> Furthermore, in the remove function, the calls to free_irq are moved up to prevent a possible reference in the interrupt handler to resources freed by power_supply_unregister.

As most of the charger chips come with two kinds of safety features related to timing: 1. Watchdog Timer (interms of seconds/mins) 2. Safety Timer (interms of hours) This patch adds these to fault causes in POWER_SUPPLY_PROP_HEALTH_* enums so that whenever there is either watchdog timeout or safety timer timeout driver could notify the user space accurately about the fault and will also be helpful for debug.
