Subject: [PATCH] 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.
