ab8500_bmdata: Export abx500_res_to_temp tables for hwmon

2013-04-17T00:38:10+00:00

This patch exports the thermistor resistance-to-temperature tables, so that the hwmon driver can access them, and also adds the corresponding table size variables. Signed-off-by: Hongbo Zhang Acked-by: Guenter Roeck Signed-off-by: Anton Vorontsov

This patch adds const attributes to AB8500 power and temperature related read-only data arrays. Signed-off-by: Hongbo Zhang Signed-off-by: Anton Vorontsov

ab8500_bmdata: Eliminate CamelCase warning of some variables

2013-04-17T00:33:34+00:00

Some AB8500 power related variable names don't comply with kernel coding rules, any new patch using these variables will result in CamelCase warnings from checkpatch.pl, this patch re-name these variables. Signed-off-by: Hongbo Zhang Signed-off-by: Anton Vorontsov

ab8500-bm: Add support for the new ab8540 platform

2013-03-07T04:35:48+00:00

Provide AB8540 platform specific information required to run the Battery Management subsystem on AB8540 based devices. For this to happen we see the introduction of separate platform specific data structures and a means in which to process them. Signed-off-by: Lee Jones

ab8500-fg: Add power cut feature for ab8505 and ab8540

2013-03-07T04:35:36+00:00

Add support for a power cut feature which allows user to configure when ab8505 and ab8540 based platforms should shut down system due to low battery. Signed-off-by: Lee Jones

Merge tag 'for-v3.9' of git://git.infradead.org/battery-2.6

2013-02-20T18:19:07+00:00

Pull battery updates from Anton Vorontsov: "Four new drivers: - goldfish_battery: This is Android Emulator battery driver. Originally from Google, but Intel folks reshaped it for mainline - pm2301_charger: A new driver for ST-Ericsson 2301 Power Management chip, uses AB8500 battery management core - qnap-poweroff: The driver adds poweroff functionality for QNAP NAS boxes - restart-poweroff: A generic driver that implements 'power off by restarting'. The actual poweroff functionality is implemented through a bootloader, so Linux' task is just to restart the box. The driver is useful on Buffalo Linkstation LS-XHL and LS-CHLv2 boards. Andrew Lunn worked on submitting the driver (as well as qnap-poweroff above). Additionally: - A lot of fixes for ab8500 drivers. This is a part of efforts of syncing internal ST-Ericsson development tree with the mainline. Lee Jones @ Linaro worked on compilation and reshaping these series. - New health properties for the power supplies: "Watchdog timer expire" and "Safety timer expire" - As usual, a bunch of fixes/cleanups here and there" * tag 'for-v3.9' of git://git.infradead.org/battery-2.6: (81 commits) bq2415x_charger: Add support for offline and 100mA mode generic-adc-battery: Fix forever loop in gab_remove() goldfish_battery: Add missing GENERIC_HARDIRQS dependency da9030_battery: Include notifier.h bq27x00_battery: Fix reporting battery temperature power/reset: Remove newly introduced __dev* annotations lp8727_charger: Small cleanup in naming ab8500_btemp: Demote initcall sequence ds2782_battery: Add power_supply_changed() calls for proper uevent support power: Add battery driver for goldfish emulator u8500-charger: Delay for USB enumeration ab8500-bm: Remove individual [charger|btemp|fg|chargalg] pdata structures ab8500-charger: Do not touch VBUSOVV bits ab8500-fg: Use correct battery charge full design pm2301: LPN mode control support pm2301: Enable vbat low monitoring ab8500-bm: Flush all work queues before suspending ab8500-fg: Go to INIT_RECOVERY when charger removed ab8500-charger: Add support for autopower on AB8505 and AB9540 abx500-chargalg: Add new sysfs interface to get current charge status ... Fix up fairly straightforward conflicts in the ab8500 driver. But since it seems to be ARM-specific, I can't even compile-test the result..

ab8500_bm: Recharge condition not optimal for battery

2013-01-16T01:43:46+00:00

Today the battery recharge is determined with a voltage threshold. This voltage threshold is only valid when the battery is relaxed. In charging algorithm the voltage read is the loaded battery voltage and no compensation is done to get the relaxed voltage. When maintenance charging is not selected, this makes the recharging condition to almost immediately activate when there is a discharge present on the battery. Depending on which vendor the battery comes from this behavior can wear out the battery much faster than normal. The fuelgauge driver is responsible to monitor the actual battery capacity and is able to estimate the remaining capacity. It is better to use the remaining capacity as a limit to determine when battery should be recharged.

Drivers: power: remove __dev* attributes.

2013-01-03T23:57:14+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

ab8500_bm: Always send platform specific battery information via pdata

2012-12-11T08:43:54+00:00

Currently the AB8500 battery management subsystem receives platform specific information via two different means depending on how the platform is booted. If DT is not enabled, a reference to a *_bm_data data structure containing each platform specific attribute is passed though platform_data. However, if DT is enabled, then platform_data is empty and the reference is gained though a DT specific probe function. There are two issues here 1) the same reference is being collected each time and 2) the DT way doesn't allow any provisions to select different platform specific attributes, which kind of defeats the object.
