* apm_power: check I.intval for zero value, we use it as the divisorAnton Vorontsov2008-02-021-0/+3

* apm_power: support using VOLTAGE_* properties for apm calculationsDmitry Baryshkov2008-02-021-21/+70
| | | | | | | | It's pretty dummy, but useful for batteries for which we can only get voltages. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Signed-off-by: Anton Vorontsov <cbou@mail.ru>
* power supply : use class iteration apiDave Young2008-01-251-48/+68
| | | | | | | | | | Convert to use the class iteration api. Signed-off-by: Dave Young <hidave.darkstar@gmail.com> Cc: Anton Vorontsov <cbou@mail.ru> Cc: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* apm_power: calculate to_full/to_empty time using energyAnton Vorontsov2007-10-041-25/+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 Vorontsov2007-10-041-10/+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 Vorontsov2007-10-041-12/+10Star
| | | | | | | | 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>
* Power supply class and drivers: remove non obligatory return statementsAnton Vorontsov2007-07-151-4/+0Star
| | | | | | | Per Jeff Garzik request. Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: Anton Vorontsov <cbou@mail.ru>
