90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
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.

6cfc2a2354 power_supply: Mark da9052 driver as broken
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.

93278d151e power_supply: Drop usage of nowarn variant of sysfs_create_link()
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!

34aed73df3 s3c_adc_battery: Average over more than one adc sample
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.

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.)

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.

8351665195 power_supply: allow a power supply to explicitly point to powered device
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.

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.

9c9cf9e263 max8925_power: Fix incorrect voltage and current calculation
The datasheet indicates a 12 bit value is returned for i2c
registers for voltage and current.  Code was assuming 8 bits.
But default for chip is 12 bit return value.

Voltage is returned in 2mV units  -- adjust to return as uV
per linux power spec

Adjust current calculation to return units in uA.

The 'val' is a 'unsigned char', so it is never less than zero.

629bcb4b72 collie_battery: Get rid of irq_to_gpio usage
Since 9d08d5d77a, irq_to_gpio() is no
longer available but still in use by collie_battery.c. As it's just
for a debug message, just get rid of this call.
