From 24afca6cf30a4f6e5c95e673bf10f78d16a27a73 Mon Sep 17 00:00:00 2001 From: Andy Green Date: Wed, 19 Nov 2008 17:09:32 +0000 Subject: introduce-bq27000-battery-driver.patch This is a driver for the bq27000 found in the Highcell A5 battery, and the platform device stuff for it for GTA02. It is a Power Supply Class battery device. The driver doesn't contain an HDQ engine but accepts pointers from the platform data to the HDQ action routines; our platform data plugs it into the FIQ HDQ engine stuff. The Power Supply class exposes the battery down /sys so you can find out battery status by doing the equivalent of this bash command for i in capacity charge_full current_now present status technology temp time_to_empty_now time_to_full_now type voltage_now ; do echo -n "$i " ; cat /sys/devices/platform/bq27000-battery.0/power_supply/bat/$i ; done Here is the kind of result you get from a battery discharging capacity 0 charge_full 1215585 current_now 183375 present 1 status Discharging technology Li-ion temp 276 time_to_empty_now 0 time_to_full_now 3932100 type Battery voltage_now 2761000 Note that temp is in 1/10 degrees C, other values are in uV, uA, uW. The time_to_* reported are bogus, but that is what the battery actually reports. We can make more mappings to entries in power_supply class but this is enough to get started with.
