sbs-battery: Add dt to power_supply struct

2013-06-29T01:20:56+00:00

By passing in the dt node of this device, we enable the logic for linking
power_supplies together from dt. This is specified by adding a
"power-supplies" property with a phandle to the charger for a given
supply.

Enable this logic now for the sbs-battery driver.

sbs-battery: Use of_match_ptr() macro

2013-04-01T03:37:26+00:00

This eliminates having an #ifdef returning NULL for the case when OF is
disabled.

power: remove use of __devexit

sbs-battery: Probe should try talking to the device

2012-09-20T21:57:52+00:00

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.

sbs-battery: Don't trigger false supply_changed event

2012-06-20T02:26:40+00:00

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.

sbs-battery.c: Capacity attr = remaining relative capacity

2012-05-06T03:05:07+00:00

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.

power_supply: Convert i2c drivers to module_i2c_driver
