"[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.

USB: transceiver changes for 3.4
Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers.
We have known for quite a long time that struct otg_transceiver was
a bad name for the structure, considering transceiver is far from
being OTG-specific (see 4e67185).
Different tree maintainers picked up independently generated
trivial compile fixes based on linux-next testing, resulting
in some cases where a file would have got more than one addition
of module.h once everything was all merged together.
Delete any duplicates so includecheck isn't complaining about
anything related to module.h/export.h changes.

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:
drivers/power/da9052-battery.c: In function 'da9052_bat_read_volt':
drivers/power/da9052-battery.c:293:2: error: implicit declaration of function 'da9052_adc_manual_read' [-Werror=implicit-function-declaration]

drivers/power/da9052-battery.c:348:1: warning: control reaches end of non-void function [-Wreturn-type]
cc1: some warnings being treated as errors
The fix for MFD part will probably go post -rc1 (or in the next merge
window), so let's disable the driver for now.

The function is not exported to modules, plus we do want to catch anyone

'powers' symlink to a directory, probably under a different name to not
break ABI).

Some sources for adc battery information provide only inaccurate results
where the read value differs from the real value with positive and negative
offsets. For such sources it can be more accurate to collect two or more
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.
For unset sample-number-values a default of 1 is assumed.

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.)

If a power supply has a scope of "Device", then allow the power supply
to indicate what device it actually powers. This is represented in the
power supply's sysfs directory as a symlink named "powers", which points to
the sysfs directory of the powered device.
If the device has children, then the sub-devices are also powered by
the same power supply.

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.
