* | POWER: TWL6030_BCI: Watchdog timer handlingGraeme Gregory2012-02-011-3/+17
| | | | | | | | | | | | | | | | This patch added handling for charger watchdog during battery charging process. Change-Id: Ica69bbf56159501ac14b341b42e39ba066271a81 Signed-off-by: Volodymyr Riazantsev <v.riazantsev@ti.com>
* | POWER: TWL6030_BCI: Change definitions from uV to mVGraeme Gregory2012-02-011-24/+29
| | | | | | | | | | | | | | | | | | This patch corrects the uV/mV confusion in the driver. All values are stored in mV and returned to userspace in uV to maintain alignment with the regulator framework voltages.

* | OMAP4: Battery charging: Reduce bq2415x watchdog timeoutOleksandr Kozaruk2011-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | bq2415x has 32 second watchdog timer. If within 32 second the watchdog timer is not reset then the charge is terminated. The work to reset watchdog was scheduled every 30 seconds, and sometimes time out expired. Reduce schedule period to 20 seconds to reset the watchdog more frequently.

* | OMAP4: battery charger: Don't check battery presence in interrupt.Oleksandr Kozaruk2011-12-141-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the battery charging process interrupts can occur and software must read the reason of the interrupt. One of the reasons is battery removed/insert event, which is already analyzed in interrupt service routine. During AC removal, due to transient reading battery ID resistor may return low value and absence of battery could be falsely detected. Checking battery presence in ISR prevents reading the reason of interrupt, which should be done.

* | pda_power: add support for using otg transceiver eventsDima Zavin2011-07-111-12/+59
| | | | | | | | | | | | | | | | | | | | | | | | If the platform data sets the use_otg_notifier flag, the driver will now register an otg notifier callback and listen to transceiver events for AC/USB plug-in events instead. This would normally be used by not specifying is_xx_online callbacks and not specifying any irqs so the state machine is completely driven from OTG xceiver events.

| * power: Make test_power driver more dynamic.John Stultz2011-05-201-10/+266
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 2008 Masashi YOKOTA <yokota@pylone.jp> created the virtual battery driver found here: http://downloads.pylone.jp/src/virtual_battery/virtual_battery-0.0.1.tar.bz2 It found use out of tree, but was never merged upstream. Since then the test_power driver has been merged, which provides very similar functionality. This patch extends the test_power driver to be more dynamic at runtime, by merging portions of the Virtual Battery Driver by Masashi YOKOTA. With this patch, I can tweak the values in: /sys/module/test_power/parameters/* and watch the behavior of the gnome power managment daemon or other battery UI software.

If the battery isn't present, then a few undesirable things happen. The first was excessive reporting of failed properties. This was fixed by instead returning ENODATA for all properties other than PRESENT if the battery isn't present. That way the callers can identify the difference between a failure and the battery not being there. The next issue was in the suspend logic. It was found that if the battery wasn't present, then it would return a failure, preventing the system from going into suspend. If there is no battery present, the io is expected to fail, so in that case, we shouldn't return the failure and just acknowledge that it was expected. I also found that when a gpio was used, i didn't maintain the internal is_present state properly. I added a set of that to fix that. Lastly, the code to see io's fail and figure out that the battery isn't present when not using a gpio had a problem. In that code, it looked for the read to fail and if it did, then handled it. The problem is that in function to get the property, it first writes a value and that write can fail, causing the code to never reach the logic after the read. Fix is to move the logic till after the write. Signed-off-by: Rhyland Klein <rklein@nvidia.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for polling the battery state and generating a power_supply_changed() event if it has changed. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Tested-by: Grazvydas Ignotas <notasas@gmail.com>
| | | * bq27x00: Cache battery registersLars-Peter Clausen2011-02-221-121/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a register cache to the bq27x00 battery driver. Usually multiple, if not all, power_supply properties are queried at once, for example when an uevent is generated. Since some registers are used by multiple properties caching the registers should reduce the number of reads. The cache is valid for 5 seconds this roughly matches the internal update interval of the current register for the bq27000/bq27200. Fast changing properties(*_NOW) which can be obtained by reading a single register are not cached. It will also be used in the follow up patch to check if the battery status has been changed since the last update to emit power_supply_changed events.

| | | * bq27x00: Add bq27000 supportLars-Peter Clausen2011-02-222-15/+183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the bq27000 battery to the bq27x00 driver. The bq27000 is similar to the bq27200 except that it uses the HDQ bus instead of I2C to communicate with the host system. The driver is implemented as a platform driver. The driver expects to be provided with a read callback function through its platform data. The read function is assumed to do the lowlevel HDQ handling and read out the value of a certain register.

| | | * bq27x00: Prepare code for addition of bq27000 platform driverLars-Peter Clausen2011-02-221-47/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch simplifies the drivers data structure and moves code to be shared by the bq27000 and bq27200/bq27500 init functions into a common function. This patch has no functional changes, it only moves code around.
