Description

The battemp value (on
/sys/devices/platform/s3c2410-i2c/i2c-adapter/i2c-0/0-0008) starts at -10, and
slowly climbs (currently it's at 9-10, connected to the USB host the whole
time). The values are obviously bogus if interpreted as °C; the ambient
temperature is at least 20°C, and the battery was not stored in a freezer before
being put on the phone.

The comments on
/home/cesarb/scratch/src/openmoko/openmoko/trunk/src/target/kernel/patches/gta01-pcf50606.patch
imply the value should be on °C; it's also possible that the comments are bogus,
and the temperature unit is something else (if that's the case, converting to °C
or Kelvin would be useful).

Does not look like we are going to address it any further than it is addressed. For GTA02, the HDQ temperature is accurate in 1/10th degree C (see /sys/class/power_supply/bat/temp )
