2009-06-04GTA02: bq27000 report current chargePaul Fertser
Using HAL for E's battery gadget highlighted an oddity: the kernel exposed last full charge property but didn't expose current charge property. This resulted in the wrong computation of current battery capacity by E's gadget (and probably other programs as well). This patch exposes a corresponding bq27000 register to make E battery gadget happy (it is still not showing correct values because of bugs in HAL resulting in 3 batteries (apm emulation and usb supply being bogus here) instead of one).

This patch adds the call to the worker in bq27000_battery_external_power_changed. Now (un)plugging the USB cable effects the battery status soon.

2009-03-25Fewer HDQ errors on 3D7KWerner Almesberger
If no battery is connected, we periodically get a burst of HDQ error messages (at least on 3D7K), interrupting whatever we're doing on the console. This patch reduces this to only one message per sequence of errors, and one more message if communication with HDQ is successful later. Signed-off-by: Werner Almesberger <werner@openmoko.org>

2009-02-08power: pcf50633 wall charger current limit fixRask Ingemann Lambertsen
Hi. The recent patch to fix a USB current limit violation when turning the device off triggered a bug in setting the battery charge current limit. We now get a charge current limit of 0 mA on the GTA02 when plugging in the wall charger (just as when setting 1000 mA in /sys/class/[...]/chg_curlim). This patch fixes it (and a comment typo). Tested on a GTA02 with a wall charger. Signed-off-by: Rask Ingemann Lambertsen <rask@sygehus.dk>

2009-02-05fix-pcf50633-set-charging-limit-with-usb-limit.patchAndy Green
Cedric noticed that when he turned his GTA02 OFF while hooked to a "dumb" USB charger that should only be asked for 100mA, suddenly much more current was demanded. When PMU enters PMU standmy when we go OFF, its USB current limit is reset to the variant default of 500mA. Since we previously had the charging current limit fixed at 1A, it meant we immediately charge at 500mA. This patch makes the charging limit follow the USB current limit, so that even when we go off, no more than the last authorized amount of current will be taken, even if the USB current limit is later broken by the variant default.
