2012-09-20da9052-battery: Don't free IRQ that wasn't requestedDan Carpenter
We should decrement "i" before doing the free_irq(). If we call this because request_threaded_irq() failed then we don't want to free the thing which failed. Or in the case where we get here because power_supply_register() failed then the original codes does a read past the end of the array.

2012-09-20sbs-battery: Probe should try talking to the deviceOlof Johansson
Turns out this driver doesn't actually try talking to the device at probe time, so if it's incorrectly configured in the device tree or platform data (or if the battery has been removed from the system), then probe will succeed and every access will sit there and time out. The end result is a possibly laggy system that thinks it has a battery but can never read status, which isn't very useful. Instead, just read any register (I chose status) at probe, and if that fails, don't register the device.

2012-09-20smb347-charger: Fix battery status reporting logic for charger faultsRamakrishna Pallala
This patch checks for charger status register for determining the battery charging status and reports Discharing/Charging/Not Charging/Full accordingly. This patch also adds the interrupt support for Safety Timer Expiration. This interrupt is helpful in debugging the cause for charger fault.

2012-09-20pda_power: Fix ac_draw usage before it being setPaul Parsons
When I reboot my iPAQ hx4700 in its cradle, the battery will not begin to charge even though the AC supply is connected. Charging will start only after the PDA power driver is tickled by some other power event, such as reseating the iPAQ in its cradle or connecting the USB cable. The problem lies in pda_power_probe(), where ac_draw is used by the call to update_charger() before being set by the call to regulator_get(). Moving the regulator_get() call to before the update_charger() call fixes the problem.

2012-08-22power_supply: Add new power supply properties CHARGE_CURRENT/VOLTAGE_MAXRamakrishna Pallala
There are different types of chargers avalibale like AC, Solar, USB, etc.. Even in USB we have different types SDP/DCP/CDP/ACA and all these chargers have different o/p ratings. For example SDP supports only 500mA of charge current whereas AC charger can support upto 8A or more. Similarly batteries also come with charge current and voltage ratings and these ratings vary depending on its capacity and the technology used. This patch adds two new power supply properties CONSTANT_CHARGE_CURRENT_MAX and CONSTANT_CHARGE_CURRENT_MAX.

2012-08-13workqueue: use mod_delayed_work() instead of cancel + queueTejun Heo
Convert delayed_work users doing cancel_delayed_work() followed by queue_delayed_work() to mod_delayed_work(). Most conversions are straight-forward. Ones worth mentioning are, * drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always use mod_delayed_work() and cancel loop in edac_mc_reset_delay_period() is dropped. * drivers/platform/x86/thinkpad_acpi.c: No need to remember whether watchdog is active or not. @fan_watchdog_active and related code dropped. * drivers/power/charger-manager.c: Seemingly a lot of delayed_work_pending() abuse going on here. [delayed_]work_pending() are unsynchronized and racy when used like this. I converted one instance in fullbatt_handler(). Please conver the rest so that it invokes workqueue APIs for the intended target state rather than trying to game work item pending state transitions. e.g. if timer should be modified - call mod_delayed_work(), canceled - call cancel_delayed_work[_sync](). * drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling() simplified. Note that round_jiffies() calls in this function are meaningless. round_jiffies() work on absolute jiffies not delta delay used by delayed_work. v2: Tomi pointed out that __cancel_delayed_work() users can't be safely converted to mod_delayed_work(). They could be calling it from irq context and if that happens while delayed_work_timer_fn() is running, it could deadlock. __cancel_delayed_work() users are dropped.

2012-07-19pda_power: remove IRQF_SAMPLE_RANDOM which is now a no-opTheodore Ts'o
With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a no-op; interrupt randomness is now collected unconditionally in a very low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM flag was scheduled to be removed in 2009 on the feature-removal-schedule, so this patch is preparation for the final removal of this flag.

2012-07-16olpc-battery: Add VOLTAGE_MAX_DESIGN propertyRichard A. Smith
upowerd wants to compute the energy in the battery by looking at this property. If it's not present then it falls back on using the reported voltage of the battery at time upowerd loads. That's close but also means that every time you boot you get a slightly different energy capacity. Adding the VOLTAGE_MAX_DESIGN property allows upowerd to compute the same energy every time.

2012-07-13power_supply: Add min/max alert properties for CAPACITY, TEMP, TEMP_AMBIENTRamakrishna Pallala
Minimum and maximum alerts on power supply properties will help or allow the user space to "proactively" create policies like connect/disconnect charger or stop/start the user apps based on capacity or temperature parameters. These parameters can be used to avoid unnecessary polling from user space and even from kernel space if the underlying HW can support INT triggers (ex: max17042/47). This patch adds the following power supply alert type properties: CAPACITY_ALERT_MIN CAPACITY_ALERT_MAX TEMP_ALERT_MIN TEMP_ALERT_MAX TEMP_AMBIENT_ALERT_MIN TEMP_AMBIENT_ALERT_MAX Signed-off-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>
