2010-02-27power_supply: bq27x00: fix voltage and current unitsGrazvydas Ignotas1-3/+3
The chip returns voltage and current in mV and mA, but power supply class uses uV and uA, so add missing conversion. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
2010-02-27power_supply: bq27x00: add status and time propertiesGrazvydas Ignotas1-2/+79
The BQ27x00 series of chips can report time-to-empty and time-to-full, so let's add corresponding properties. Also report charge status based on status flag register. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
2010-02-16power_supply: bq27x00: add BQ27500 supportGrazvydas Ignotas1-28/+49
BQ27500 is newer fuel gauge chip from TI with slightly changed register layout and some different register semantics. Add new i2c ID for it and handle differences where needed. Also rename bq27200 functions to bq27x00, as they are no longer bq27200 specific.

2010-02-16power_supply: bq27x00: fix temperature conversionGrazvydas Ignotas1-2/+2
The power supply class requires tenths of degree Celsius. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Acked-by: Rodolfo Giometti <giometti@linux.it> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
2010-02-16power_supply: bq27x00: remove unused struct fieldsGrazvydas Ignotas1-4/+0
These are probably leftover from old TI code. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Acked-by: Rodolfo Giometti <giometti@linux.it> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
2010-02-16power_supply: bq27x00: remove double endian swapGrazvydas Ignotas1-8/+3
The bq27x00 registers are little endian, so just read them as such and don't do double endian swap on LE machines. This also gets rid of strange looking shift that was done after reading 8bit register because endian swap in bq27x00_read() was messing it up.

2009-03-30trivial: Fix misspelling of "Celsius".Adam Buchbinder1-1/+1
A few comments say "Celcius"; this fixes them. No code changes. Signed-off-by: Adam Buchbinder <adam.buchbinder@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2008-09-26bq27x00_battery: use unaligned access helperHarvey Harrison1-3/+2
Remove hand-rolled get_unaligned_be16, this points to a possible bug as bq27x00_read does another endian byteswap which sparse notices: drivers/power/bq27x00_battery.c:81:14: warning: cast to restricted __be16 Which should probably be checked.

2008-09-01power_supply: Support for Texas Instruments BQ27200 battery managersRodolfo Giometti1-0/+382
These battery managers came in two different packages: one for I2C busses (BQ27200) and one for HDQ busses (BQ27000). This driver currently supports only the I2C chip version but the code is designed in order to easily allow the HDQ chip version integration.
