2011-03-16bq20z75: Fix issues with present and suspendRhyland Klein
There are a few issues found around the battery not being present. If the battery isn't present, then a few undesirable things happen. The first was excessive reporting of failed properties. This was fixed by instead returning ENODATA for all properties other than PRESENT if the battery isn't present. That way the callers can identify the difference between a failure and the battery not being there. The next issue was in the suspend logic. It was found that if the battery wasn't present, then it would return a failure, preventing the system from going into suspend. If there is no battery present, the io is expected to fail, so in that case, we shouldn't return the failure and just acknowledge that it was expected. I also found that when a gpio was used, i didn't maintain the internal is_present state properly. I added a set of that to fix that. Lastly, the code to see io's fail and figure out that the battery isn't present when not using a gpio had a problem. In that code, it looked for the read to fail and if it did, then handled it. The problem is that in function to get the property, it first writes a value and that write can fail, causing the code to never reach the logic after the read. Fix is to move the logic till after the write. Signed-off-by: Rhyland Klein <rklein@nvidia.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>

2011-02-22bq27x00: Cache battery registersLars-Peter Clausen
This patch adds a register cache to the bq27x00 battery driver. 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.

2011-02-22bq27x00: Add bq27000 supportLars-Peter Clausen
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.

2011-02-22power_supply: Initialize changed_work before calling device_addLars-Peter Clausen
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.

2011-02-22power_supply: Ignore -ENODATA errors when generating ueventsLars-Peter Clausen
Sometimes a driver can not report a meaningful value for a certain property and returns -ENODATA. Currently when generating a uevent and a property return -ENODATA it is treated as an error an no uevent is generated at all. This is not an desirable behavior. This patch adds a special case for -ENODATA and ignores properties which return this error code when generating the uevent.

2011-01-14power_supply: Add MAX17042 Fuel Gauge DriverMyungJoo Ham
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.

The patches adding support for CURRENT_NOW, VOLTAGE_NOW, CHARGE_NOW and CHARGE_FULL_DESIGN were based on a tree not including c566d299 ("olpc_battery: Ambient temperature is not available on XO-1.5") and therefore only modified the then-common, now-XO-1 properties list.
