Usually multiple, if not all, power_supply properties are queried at once, for example when an uevent is generated. Since some registers are used by multiple properties caching the registers should reduce the number of reads. The cache is valid for 5 seconds this roughly matches the internal update interval of the current register for the bq27000/bq27200. Fast changing properties(*_NOW) which can be obtained by reading a single register are not cached. It will also be used in the follow up patch to check if the battery status has been changed since the last update to emit power_supply_changed events.

| | | * bq27x00: Add bq27000 supportLars-Peter Clausen2011-02-222-15/+183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the bq27000 battery to the bq27x00 driver. The bq27000 is similar to the bq27200 except that it uses the HDQ bus instead of I2C to communicate with the host system. The driver is implemented as a platform driver. The driver expects to be provided with a read callback function through its platform data. The read function is assumed to do the lowlevel HDQ handling and read out the value of a certain register.

| | | * power_supply: Initialize changed_work before calling device_addLars-Peter Clausen2011-02-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling device_add causes an inital uevent for that device to be generated. The power_supply uevent function calls the drivers get_property function, which might causes the driver to update its state, which again might causes the driver to call power_supply_changed(). Since the power_supplys changed_work has not been initialized at this point the behavior is undefined and can result in an OOPS. This patch fixes the issue by initializing the power_supplys changed_work prior to adding the power_supplys device to the device tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MAX17042 is a fuel gauge with an I2C interface for lithium-ion betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit registers. Besides, MAX17042 has much more features than MAX17040; e.g., a thermistor, current and current accumulation measurement, battery internal resistance estimate, average values of measurement, and others. This patch implements a driver for MAX17042. In this initial release, we have implemented the most basic features of a fuel gauge: measure the battery capacity and voltage.

This is because current is negative while the battery is discharging. Fix the check introduced by commit b0525b48 so that time_to_empty_now is reported correctly during discharge and as zero while charging.
