| * apm_power: calculate to_full/to_empty time using energyAnton Vorontsov2007-10-051-25/+53
| | | | | | | | | | | | | | This patch adds ability to calculate time using energy. Needed to calculate time_to_full for PMU batteries. Signed-off-by: Anton Vorontsov <cbou@mail.ru>
| * apm_power: improve battery finding algorithmAnton Vorontsov2007-10-051-10/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch, if use_for_apm unspecified, apm_power able to choice batteries according to their charge only. This patch adds ability to choice batteries according to their charge, energy, use_for_apm flag, and fallback to any battery if it failed to decide. Patch is mandatory to report Apple PMU batteries through legacy /proc/apm interface using power supply class. Signed-off-by: Anton Vorontsov <cbou@mail.ru>
| * apm_power: fix obviously wrong logic for time reportingAnton Vorontsov2007-10-051-12/+10
| | | | | | | | | | | | | | | | Prior to this patch, apm_power was unable to report "to empty"/"to full" time for batteries that hardware-report these values, such as Apple PMU batteries. Signed-off-by: Anton Vorontsov <cbou@mail.ru>

* | Driver core: change add_uevent_var to use a structKay Sievers2007-10-122-14/+6
|/ | | | | | | | | | | | | | | | | | This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

* Don't compile the PMU power driver on 64-bit PowerPCPaul Mackerras2007-07-231-1/+1
| | | | | | | | | | | | | | | | As reported by Stephen Rothwell, an allmodconfig build on 64-bit PowerPC reports these errors: ERROR: "pmu_batteries" [drivers/power/pmu_battery.ko] undefined! ERROR: "pmu_battery_count" [drivers/power/pmu_battery.ko] undefined! ERROR: "pmu_power_flags" [drivers/power/pmu_battery.ko] undefined! This fixes the problem by not building pmu_battery.ko on ppc64. There are no battery-powered ppc64 machines with an Apple PMU, and we can be reasonably confident there never will be.

| * pda_power: clean up irq, timerJeff Garzik2007-07-151-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up pda_power interrupt handling: Prior to this patch, the driver would pass information it needed to the interrupt handler dev_id pointer, and then prompt forget it ever did so, recreating that same information after a couple passes through the timer-based state machine. This patch removes the redundant checks by passing the pda_power_supply[] pointer through the state machine. The current code passed 'irq' through the state machine, as an index to recreate the pointer, when we could more simply pass around the pointer itself. This patch makes it easier to remove the 'irq' argument in the future, in addition to cleaning up the driver today. Signed-off-by: Jeff Garzik <jeff@garzik.org>

* [BATTERY] pda_power platform driverAnton Vorontsov2007-07-103-0/+270
| | | | | | | | | | | | | | | | | | | Common power driver for PDAs and phones with one or two external power supplies (AC/USB) connected to main and backup batteries, and optional builtin charger. It's used to stop logic duplication through different embedded devices. So, power supply *logic* is here. pda_power register power supplies, and will take care about notifying batteries about power changes through external power interface. Currently, power consumption legal limits (including USB power consumption) should be handled by platform code, inside set_charge function.
