lp8727_charger: Add terminating entry for i2c_device_id table

2012-02-01T17:34:26Z

The i2c_device_id table is supposed to be zero-terminated. Signed-off-by: Axel Lin Acked-by: Milo(Woogyom) Kim Signed-off-by: Anton Vorontsov

power_supply: Fix modalias for charger-manager

2012-02-01T17:29:52Z

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Current code has the id_table, thus add MODULE_DEVICE_TABLE will automatically setup the modalias. Also make charger_manager_id static as it is only used in this driver. Signed-off-by: Axel Lin Acked-by: MyungJoo Ham Signed-off-by: Anton Vorontsov

bq27x00_battery: Fix flag register read

2012-02-01T17:27:28Z

When reading flags, bq27x00_read() argument is inverted and causes reads 2 of bytes for bq27200 and 1 byte for bq27500, while their register sizes are 1 and 2 bytes respectively. This causes bq27500 upper flag bits always to be returned as 0, causing full charge state to never be reported correctly, so fix it.

Revert "bq27x00_battery: Fix reporting status value for bq27500 battery"

2012-02-01T17:21:29Z

This reverts commit 270968c0984aeed096da3cfffb0e131f4c416166. Grazvydas Ignotas wrote: After 270968c0984ae "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. Suggested-by: Grazvydas Ignotas Acked-by: Pali Rohár Signed-off-by: Anton Vorontsov

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

2012-01-12T23:02:20Z

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 Signed-off-by: Rusty Russell

power_supply: Mark da9052 driver as broken

2012-01-10T01:14:10Z

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()

2012-01-07T11:24:51Z

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! Reported-by: Stephen Rothwell Signed-off-by: Anton Vorontsov

s3c_adc_battery: Average over more than one adc sample

2012-01-06T02:13:35Z

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 Signed-off-by: Anton Vorontsov
