module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

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.

power_supply: Mark da9052 driver as broken

2012-01-10T01:14:10+00:00

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: In function 'da9052_determine_vc_tbl_index':
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.

power_supply: Drop usage of nowarn variant of sysfs_create_link()

2012-01-07T11:24:51+00:00

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!

s3c_adc_battery: Average over more than one adc sample

2012-01-06T02:13:35+00:00

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.

power_supply: Add DA9052 battery driver

2012-01-06T02:10:02+00:00

Driver for DA9052 battery charger. This driver depends on DA9052 MFD core
dirver for definitions and methods.

This patch is functionally tested on Samsung SMDKV6410.

wait_for_completion_interruptible_timeout() may return negative value.
In this case, checking if (t > 0)  will return true if t is unsigned.

power_supply: Assume mains power by default

2012-01-06T01:50:32+00:00

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.)
