a2ebfe2fc6 power_supply: Add voltage_ocv property and use it for max17042 driver
This adds a new sysfs file called 'voltage_ocv' which gives the
Open Circuit Voltage of the battery.

This property can be used for platform shutdown policies and
can be useful for initial capacity estimations.

1ef3d8fb4d max17042_battery: Fix a couple buffer overflows
There are a couple issues here caused by confusion between sizeof()
and ARRAY_SIZE().  "table_size" should be the number of elements, but we
should allocate it with kcalloc() so that we allocate the correct number
of bytes.

In max17042_init_model() we don't allocate enough space so we go past
the end of the array in max17042_read_model_data() and
max17042_model_data_compare().

In max17042_verify_model_lock() we allocate the right amount of space
but we call max17042_read_model_data() with the wrong number of elements
and also in the for loop we go past the end of the array.

"[RFC PATCH 0/2] audit of linux/device.h users in include/*"
 		https://lkml.org/lkml/2012/3/4/159
 --
 
 Nearly every subsystem has some kind of header with a proto like:
 
 	void foo(struct device *dev);
 
 and yet there is no reason for most of these guys to care about the
 sub fields within the device struct.  This allows us to significantly
 reduce the scope of headers including headers.  For this instance, a
 reduction of about 40% is achieved by replacing the include with the
 simple fact that the device is some kind of a struct.
 
 Unlike the much larger module.h cleanup, this one is simply two
 commits.  One to fix the implicit <linux/device.h> users, and then
 one to delete the device.h includes from the linux/include/ dir
 wherever possible.

 Fix up files in fs/ and lib/ dirs to only use module.h if they really

 These are trivial in scope vs. the work done previously.  We now have
 things where any few remaining cleanups can be farmed out to arch or
 subsystem maintainers, and I have done so when possible.  What is
 remaining here represents the bits that don't clearly lie within a
 single arch/subsystem boundary, like the fs dir and the lib dir.

of the implicit uses of linux/device.h within include/*

Yes, this was created by "cheating" -- i.e. the headers were

the two commits were reordered.  This ensures we don't introduce

Grazvydas Ignotas wrote:

After 270968c098 "bq27x00_battery: Fix reporting status value for
bq27500 battery" status doesn't seem to be reported correctly when the
battery is close to fully charged state. It reports "Not charging"
while in fact there is >130mA current flowing to the battery according
to current_now.

This status report seems to be based on CHG bit in status register,
but looking at the datasheet the description says "(Fast) charging
allowed", which I guess means that the chip recommends charging and
not that charging is actually going on? If you check the bit while
battery is discharging and it's not full, the bit is also set.

There are some problems with MFD part of this driver, so the
driver fails to build:

The fix for MFD part will probably go post -rc1 (or in the next merge

value sample and use the average of all collected values.

This patch adds pdata options volt_samples, current_samples and
backup_volt_samples to specifiy the number of samples to collect,
reads the specified number of samples and calculates the average of those.

2530daa187 power_supply: Assume mains power by default
If no power class device is found in power_supply_is_system_supplied(),
the function currently returns 0, which basically means that the system
is supposed to be running on battery. In practice, mobile devices tend
to always implement at least one power class device and more often two
(battery and AC adapter). Systems with no registered power class
devices are more likely to be desktop systems, where the system is
always powered by mains.

So, change the default return value of
power_supply_is_system_supplied() from 0 (running on battery) to 1
(running on mains.)

25a0bc2dfc power_supply: add SCOPE attribute to power supplies
This adds a "scope" attribute to a power_supply, which indicates how
much of the system it powers.  It appears in sysfs as "scope" or in
the uevent file as POWER_SUPPLY_SCOPE=.  There are presently three
possible values:
	Unknown - unknown power topology
	System - the power supply powers the whole system
	Device - it powers a specific device, or tree of devices

A power supply which doesn't have a "scope" attribute should be assumed to
have "System" scope.

In general, usermode should assume that loss of all System-scoped power
supplies will power off the whole system, but any single one is sufficient
to power the system.

f17ef9b2da power: Make test_power driver more dynamic.
In 2008 Masashi YOKOTA <yokota@pylone.jp> created the virtual
battery driver found here:
http://downloads.pylone.jp/src/virtual_battery/virtual_battery-0.0.1.tar.bz2

It found use out of tree, but was never merged upstream.
Since then the test_power driver has been merged, which provides
very similar functionality.

This patch extends the test_power driver to be more dynamic
at runtime, by merging portions of the Virtual Battery Driver
by Masashi YOKOTA.

With this patch, I can tweak the values in:
/sys/module/test_power/parameters/* and watch the behavior of
the gnome power managment daemon or other battery UI software.

a7d9ace4eb bq20z75: Fix issues with present and suspend
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.

297a533b3e bq27x00: Cache battery registers
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.

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.

9777467257 power_supply: Initialize changed_work before calling device_add
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.

e1a85694e0 isp1704_charger: Detect charger after probe
If the device is booted up with cable connected, or the
module is loaded after plugging in the cable, the
notification has come and gone, so not relying on it at
probe time. Instead this checks the VBUS level manually
after probe.

bac43b2050 isp1704_charger: Detect HUB/Host chargers
To avoid breaking high speed chirp handshaking with CDP
chargers, no more then 500mA should be drawn. To make sure
of this, utilizing current_max property. After the device
has enumerated, it's safe to draw the maximum 1800mA as
defined in the Battery Charging Specification. This can be
also used with normal USB connection if the controller sends
ENUMERATED notification with the milliamps as data.

From now on the online property indicates VBUS, present
property if there is a charger and current_max the milliamps
possible to draw from VBUS.

86af95039b ds2760_battery: Fix calculation of time_to_empty_now
A check against division by zero was modified in commit b0525b48.
Since this change time_to_empty_now is always reported as zero
while the battery is discharging and as a negative value while
the battery is charging. 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.

fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

bbabb158f0 power_supply: Fix regression for 'type' property
Commit 5f487cd34f (power_supply: Use
attribute groups) causes a regression the power supply core does not
export the 'type' attribute anymore.

POWER_SUPPLY_PROP_TYPE is handled by the power supply core without the
low-level driver, so power_supply_attr_is_visible() must always return
the entry as readable.

This patch adds support for writeable power supply properties and
exposes them as writeable to sysfs.

A power supply implementation must implement two new function calls in
order to use that feature:

  int set_property(struct power_supply *psy,
                   enum power_supply_property psp,
                   const union power_supply_propval *val);

  int property_is_writeable(struct power_supply *psy,
                            enum power_supply_property psp);

b1458fb57d wm97xx_battery: Quieten sparse warning (bat_set_pdata not declared)
This patch fixes following sparse warning:

drivers/power/wm97xx_battery.c:311:6: warning: symbol 'wm97xx_bat_set_pdata' was not declared. Should it be static?

Note that we can't just include linux/wm97xx_batt.h because the header
is deprecated, and so this pops up:

In file included from drivers/power/wm97xx_battery.c:22:
include/linux/wm97xx_batt.h:6: warning: #warning This file will be removed soon, use wm97xx.h instead!

Since wm97xx_bat_set_pdata() is also deprecated (in favour of pdata
passed via AC97 bus), just workaround the issue by declaring the
function in wm97xx_battery.c.

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.
