2008-07-22Driver Core: add ability for class_for_each_device to start in middle of listGreg Kroah-Hartman1-1/+1
This mirrors the functionality that driver_for_each_device has as well. We add a start variable, and all callers of the function are fixed up at the same time. The block layer will be using this new functionality in a follow-on patch. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-02-02apm_power: support using VOLTAGE_* properties for apm calculationsDmitry Baryshkov1-21/+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>

2007-10-05apm_power: calculate to_full/to_empty time using energyAnton Vorontsov1-25/+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>
2007-10-05apm_power: improve battery finding algorithmAnton Vorontsov1-10/+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>
2007-10-05apm_power: fix obviously wrong logic for time reportingAnton Vorontsov1-12/+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>
