* power_supply: 88pm860x: Fix leaked power supply on probe failKrzysztof Kozlowski2015-01-281-0/+1
| | | | | | | | | | | Driver forgot to unregister power supply if request_threaded_irq() failed in probe(). In such case the memory associated with power supply leaked.

* Add LTC2941/LTC2943 Battery Gauge DriverMike Looijmans2015-01-223-0/+556
| | | | | | | | | | | | | | | | | | | | Both the LTC2941 and LTC2943 measure battery capacity. The LTC2943 is compatible with the LTC2941, it adds voltage and temperature monitoring, and uses a slightly different conversion formula for the charge counter. To avoid confusion with e.g. the LTC2945, the driver is called LTC2941 instead of LTC294X. v2: Fix units of measurement: uV, uA and centidegrees. v3: Correctly set configuration register. Allow negative values for the sense resistor. v4: Run checkpatch.pl and fix all errors and warnings. v5: Prefix "lltc," to devicetree properties.

| | | | | | | | | | | | To guerantee proper charing and managing batteries even in suspend, charger-manager has used rtc device with rtc framework interface.

| | | | | | | | | | | | | | | | | Add a reset driver for Renesas R-Mobile and SH-Mobile SoCs. It registers a restart handler to trigger a soft power-on reset through the R-Mobile System Controller. The priority of this restart handler is 192, to allow a watchdog driver to use priority 128. Note that we do not use syscon-reboot, as the HPB (Peripheral Bus Bridge) semaphore should be acquired on systems where both the ARM and SH core are in use.

* power: reset: ltc2952: make trigger input optionalFrans Klaver2015-01-201-32/+55
| | | | | | | | | | | | | | | | | Currently the ltc2952 supports only one button sequence to initiate powerdown. This is not always desirable, as even prolonged button presses can happen in use. Allow ltc2952 users to pick their own power down sequence, by making the trigger input optional. Since this still means that the ltc2952 may power down the platform if the power button is pressed for about 5 seconds, we still need to make sure to start the watchdog toggle to prolong the system power for as long as we need it. This will still allow the system to control power using the kill signal. Signed-off-by: Frans Klaver <frans.klaver@xsens.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ltc2952_poweroff_handler it is theoretically possible that the timer fails to start on first pass (button press), but succeeds in starting on the second (button release). This will cause the button press to be misinterpreted, and will incorrectly shut down the system. Because a picture says more than a thousand words: Expected behavior: tmr: ++++++++++ btn: -----__________----- Faulty behavior: tmr: +++++ btn: -----__________----- Legend: + timer runs _ button pressed - button depressed To prevent this from happening, check the value of the gpio before starting the timer. If the button is active, we should start the timer, else we should stop it. The situation described can now still occur if the polarity of the input pin is set incorrectly, but that at least is predictable behavior and can be detected during the first tests.

Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.

| * power / PM: Eliminate CONFIG_PM_RUNTIMERafael J. Wysocki2014-12-151-4/+0
| | | | | | | | | | | | | | | | | | | | | | After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME within #ifdef blocks depending on CONFIG_PM may be dropped now. Do that in drivers/power/pm2301_charger.c. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

| * | power: reset: adjust priority of simple syscon reboot driverStefan Agner2014-12-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, all restart handler use the priority 128, including watchdogs. Probably most SoC have a watchdog, and some of them register it also as a restart handler. But if a SoC specifies a dedicated reboot capability using this syscon driver, this is usually the preferred reboot method. Hence, raise the priority of this driver to 192.

Move notifier registration to the end of the probe function to avoid having to implement error handling.
