2014-01-06power: Add early battery capacity and voltage snapshot recordingdarbha sriharsha
If the battery gauge gets incorrect readings for capacity as 0 even for an instant soon after the kernel bootup, the board will incorrectly shut down reporting low battery though there is sufficient juice in the battery. Hence, if there is even a slight delay in correct battery capacity reporting by fuel gauge due to chip problem or coding error, this can lead to the board incorrectly shutting down as for an instant, the android framework will read the capacity as 0. Hence, adding support for recording an early snapshot value of capacity and voltage values and making these early snapshots available through sysfs entries, so that appropriate sanity tests can examine these values and flag an error if early capacity snapshot value is 0.

2012-09-20sbs-battery: Probe should try talking to the deviceOlof Johansson
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.

2012-06-19sbs-battery: Don't trigger false supply_changed eventNikolaus Voss
power_supply_changed() events are triggerd based on the return value of a get_property() call. However the property TECHNOLOGY is hard-coded to LION in this driver, thus always succeeds. So, with the battery removed, this triggers a false battery present uevent. This uevent triggers a new query via power_supply_uevent() which again starts to query all known properties and thus leads to an infinite loop of battery present/not-present uevents. This patch skips the battery presence detection for the hard-coded property TECHNOLOGY.

2012-05-05sbs-battery.c: Capacity attr = remaining relative capacityNikolaus Voss
Currently, the capacity exported by this driver refers to reg 0x0e, which is the absolute state of charge which according to SBS refers to the design capacity/ energy of the battery. It can be > 100 % and drops below 100 % for a fully charged battery with the battery aging. This is not what the user exspects of a remaining capacity indication between 0 and 100 % with 100 % referring to a fully charged battery. This is provided by SBS reg 0x0d, which is the relative state of charge referring to the full charge capacity.
