For better understanding, use specific function and definitions rather than magic numbers. New enum type for die temperature is matched with hex codes. Specific temperature names are better than 0x1, 0x2 and 0x3. And lp8727_is_high_temperature() function has better readability than comparing raw register values.

For better understanding, function name is changed. (lp8727_intr_config() is replaced with lp8727_setup_irq().) The private IRQ number is set when the IRQ is allocated successfully. This data is used for releasing the IRQ on unloading the driver. Even the IRQ number is not defined, the driver should be operated. In this case, just return as 0. In additional function lp8727_release_irq(), the workqueue is canceled and the allocated IRQ is released.

LP8727 has two IRQ threads. One is the I2C HW IRQ pin, the other is for delayed interrupt processing. But this delayed processing can be handled without additional single thread by using schedule_delayed_work() with jiffies time value.

Debounce time is configurable in the platform side. If it is not defined, the default value is 270ms. Platform data is msec unit, and this time is converted to jiffies internally. The workqueue uses this jiffies time in the interrupt handling. So debounce_jiffies is added in the private data.

LP8727 platform data is optional, so the driver should work even the platform data is NULL. To check the platform data, charging parameter data should be changed to the pointer type. Fix NULL point access problem when getting the battery properties. When the data is NULL, just return as invalid value.

If the lp8727_register_psy() gets failed, registered interrupt handler should be freed, but this is not complete solution. It has still problem. Assume that the IRQ occurs while unregistering power supply devices. Then the ISR will access to freed IRQ. From Anton's opinion, it can be resolved if re-ordering the call sequence. Register power supplies first, then create interrupt handler. Then no need to free the IRQ in _probe(). Additionally goto statements can be removed because those can be replaced with return statements. The _remove() should be changed the sequence - in reverse order of _probe() Signed-off-by: NMilo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: NAnton Vorontsov <anton.vorontsov@linaro.org>

There are charger and battery measurement feature for 88pm860x PMIC. For charger, it can support pre-charge with small current when battery is nearly exausted and then changed into fast-charge with CC&CV mode. For battery monitor, it can support battery measurement such as vbat,vsys,vchg and ibat etc,it can aslo accumulating the Coulomb value charged or discharged from battery based on Conlomb Counter, we use it to estimate battery capacity.

TI LP8788 PMU supports regulators, battery charger, RTC, ADC, backlight driver and current sinks. This patch supports the charger operations including the charger interrupt handling. The LP8788 charger driver provides configurable platform data. The charger platform data includes ADC input ID, maximum battery voltage, charging parameters and etc. The ADC input is used for getting the battery voltage and temperature. Charging parameters are used for updating the charger operations such like setting charging current and setting End-of-charge conditions. When the charging interrupt occurs, power supply uevents are generated in order to update the user-space information. For platform specific charger action, the charger_event() function can be used in the platform side.

We should decrement "i" before doing the free_irq(). If we call this because request_threaded_irq() failed then we don't want to free the thing which failed. Or in the case where we get here because power_supply_register() failed then the original codes does a read past the end of the array.

Turns out this driver doesn't actually try talking to the device at probe time, so if it's incorrectly configured in the device tree or platform data (or if the battery has been removed from the system), then probe will succeed and every access will sit there and time out. The end result is a possibly laggy system that thinks it has a battery but can never read status, which isn't very useful. Instead, just read any register (I chose status) at probe, and if that fails, don't register the device.

When I reboot my iPAQ hx4700 in its cradle, the battery will not begin to charge even though the AC supply is connected. Charging will start only after the PDA power driver is tickled by some other power event, such as reseating the iPAQ in its cradle or connecting the USB cable. The problem lies in pda_power_probe(), where ac_draw is used by the call to update_charger() before being set by the call to regulator_get(). Moving the regulator_get() call to before the update_charger() call fixes the problem.

There are different types of chargers avalibale like AC, Solar, USB, etc.. Even in USB we have different types SDP/DCP/CDP/ACA and all these chargers have different o/p ratings. For example SDP supports only 500mA of charge current whereas AC charger can support upto 8A or more. Similarly batteries also come with charge current and voltage ratings and these ratings vary depending on its capacity and the technology used. This patch adds two new power supply properties CONSTANT_CHARGE_CURRENT_MAX and CONSTANT_CHARGE_CURRENT_MAX.
