a22b41a31e sbs-battery: Probe should try talking to the device
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.

1502cfe19b smb347-charger: Fix battery status reporting logic for charger faults
This patch checks for charger status register for determining the
battery charging status and reports Discharing/Charging/Not Charging/Full
accordingly.

This patch also adds the interrupt support for Safety Timer Expiration.
This interrupt is helpful in debugging the cause for charger fault.

ec60ea5cd6 pda_power: Fix ac_draw usage before it being set
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.

2815b786c3 power_supply: Add new power supply properties CHARGE_CURRENT/VOLTAGE_MAX
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.

4b24ff7110 The tag contains just a few battery-related changes for v3.6. It's is
all pretty straightforward, except one thing.
 
 One of our patches added thermal support for power supply class, but
 thermal/ subsystem changed under our feet. We (well, Stephen, that is)
 caught the issue and it was decided[1] that I'd just delay the battery
 pull request, and then will fix it up by merging upstream back into
 battery tree at the specific commit.
 
 That's not all though: another[2] small fixup for thermal subsystem was
 needed to get rid of a warning in power supply subsystem (the warning
 was not drivers/power's "fault", the thermal registration function just
 needed a proper const annotation, which is also done by a small commit
 on top of the merge.
 
 So, to sum this up:
 - The 'master' branch of the battery tree was in the -next tree for
   weeks, was never rebased, altered etc. It should be all OK;
 - Although, for-v3.6 tag contains the 'master' branch + merge + the
   warning fix.

fa93669a19 Driver core merge for 3.6-rc1
Here's the big driver core pull request for 3.6-rc1.
 
 Unlike 3.5, this kernel should be a lot tamer, with the printk changes now
 settled down.  All we have here is some extcon driver updates, w1 driver
 updates, a few printk cleanups that weren't needed for 3.5, but are good to
 have now, and some other minor fixes/changes in the driver core.
 
 All of these have been in the linux-next releases for a while now.

With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a

low-overhead fashion; see commit 775f4b297b.  The IRQF_SAMPLE_RANDOM

5619d0ba97 olpc-battery: Add VOLTAGE_MAX_DESIGN property
upowerd wants to compute the energy in the battery by looking at this
property.  If it's not present then it falls back on using the reported
voltage of the battery at time upowerd loads.  That's close but also
means that every time you boot you get a slightly different energy
capacity.

Adding the VOLTAGE_MAX_DESIGN property allows upowerd to compute the
same energy every time.

e908c41806 power_supply: Add min/max alert properties for CAPACITY, TEMP, TEMP_AMBIENT
Minimum and maximum alerts on power supply properties will help or allow
the user space to "proactively" create policies like connect/disconnect
charger or stop/start the user apps based on capacity or temperature
parameters.

These parameters can be used to avoid unnecessary polling from user space
and even from kernel space if the underlying HW can support INT triggers
(ex: max17042/47).

This patch adds the following power supply alert type properties:

 CAPACITY_ALERT_MIN
 CAPACITY_ALERT_MAX
 TEMP_ALERT_MIN
 TEMP_ALERT_MAX
 TEMP_AMBIENT_ALERT_MIN

5da50988a1 sbs-battery: Don't trigger false supply_changed event
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.
