module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Acked-by: Mauro Carvalho Chehab

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: In function 'da9052_bat_check_presence':
drivers/power/da9052-battery.c:306:2: error: implicit declaration of function 'da9052_adc_read_temp' [-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 errorsThe fix for MFD part will probably go post -rc1 (or in the next merge
window), so let's disable the driver for now.Reported-by: Stephen Rothwell

The function is not exported to modules, plus we do want to catch anyone
who tries to create complex hierarchy (in that case we'd need to change
'powers' symlink to a directory, probably under a different name to not
break ABI).This patch fixes the following build error:
ERROR: "sysfs_create_link_nowarn" [drivers/power/power_supply.ko] undefined!

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.Signed-off-by: Heiko Stuebner

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.)Signed-off-by: Jean Delvare

Because battery health monitoring should be done even when suspended,
it needs to wake up and suspend periodically. Thus, userspace battery
monitoring may incur too much overhead; every device and task is woken
up periodically. Charger Manager uses suspend-again to provide
in-suspend monitoring.This patch allows to monitor battery health in-suspend state.

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.Signed-off-by: Jeremy Fitzhardinge

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 devicesA 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.Signed-off-by: Jeremy Fitzhardinge
