| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These battery managers came in two different packages: one for I2C busses (BQ27200) and one for HDQ busses (BQ27000). This driver currently supports only the I2C chip version but the code is designed in order to easily allow the HDQ chip version integration.

| * | power_supply: Add function to return system-wide power stateMatthew Garrett2008-09-011-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain drivers benefit from knowing whether the system is on ac or battery, for instance when determining which backlight registers to read. This adds a simple call to determine whether there's an online power supply other than any batteries.

| * | pda_power: Check and handle return value of set_irq_wakeRobert Jarzmik2008-09-011-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change in commit 2db873211ba47ef704c301f9ecf4a33413a0b649 forces the calls enable_irq_wake() and disable_irq_wake() to be balanced. But if in pda_power_suspend() the call to enable_irq_wake() fails (because attached gpio cannot wake up the CPU), the corresponding disable_irq_wake will WARN(). Fix it by storing success/failure of enable_irq_wake(). Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
* | | x86: sysfs: kill owner field from attributeParag Warudkar2008-10-201-1/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

| | | | | | | | | | | | | | | | | | | | | | | | | | This adds PROP_CHARGE_COUNTER to the power supply class (documenting it as well). The OLPC battery driver uses this for spitting out its ACR values (in uAh). We have some rounding errors (the data sheet claims 416.7, the math actually works out to 416.666667, so we're forced to choose between overflows or precision loss. I chose precision loss, and stuck w/ data sheet values), but I don't think anyone will care that much.

Note that it does an EC command for each byte, so it's pretty slow. OTOH, if you want to grab just a single byte from somewhere in the EEPROM, you can do something like: dd bs=1 count=1 skip=16 if=/sys/class/power_supply/olpc-battery/eeprom | od -x Userspace battery collection/logging information needs this.

| | | | | | | | Currently pda-power adds both ac and usb power supply units. This patch fixes it so that psu are added only if they are enabled. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Signed-off-by: Anton Vorontsov <cbou@mail.ru>
* power: fix incorrect unregistration in power_supply_create_attrs error pathAndres Salomon2008-02-021-4/+2
| | | | | | | | | | | | | In power_supply_create_attrs(), we create static attributes as referenced by power_supply_static_attrs[i]. After that, if we fail, we unregister via power_supply_static_attrs[psy->properties[i]]. This is incorrect, as psy->properties has absolutely no bearing on static attribs. This patch fixes it to unregister the correct attrib. Another line which was unnecessarily line wrapped is also unwrapped.

* power: remove POWER_SUPPLY_PROP_CAPACITY_LEVELAndres Salomon2008-02-022-15/+0
| | | | | | | | | | | | | | | | | | | | | | | The CAPACITY_LEVEL stuff defines various levels of charge; however, what is the difference between them? What differentiates between HIGH and NORMAL, LOW and CRITICAL, etc? As it appears that these are fairly arbitrary, we end up making such policy decisions in the kernel (or in hardware). This is the sort of decision that should be made in userspace, not in the kernel. If the hardware does not support _CAPACITY and it cannot be easily calculated, then perhaps the driver should register a custom CAPACITY_LEVEL attribute; however, userspace should not become accustomed to looking for such a thing, and we should certainly not encourage drivers to provide CAPACITY_LEVEL stubs. The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The OLPC battery driver is the only driver making use of this, so it's removed from there as well.
