RE: [PATCH V5 0/2] power: bq27xxx: add bq78z100

2021-03-17 Thread LI Qingwu
Hi Sebastian,

Here is the dump of the "uevent", I tested two cases, discharging current >0 
and discharging current =0.
If discharging current=0:
POWER_SUPPLY_TIME_TO_EMPTY_NOW and POWER_SUPPLY_TIME_TO_FULL_NOW are 
disappear, 
the value is "-ENODATA"
If discharging current>0:
POWER_SUPPLY_TIME_TO_FULL_NOW is disappear, 
the value is "-ENODATA"
Since I can't test charging on our hardware, I think 
"POWER_SUPPLY_TIME_TO_FULL_NOW" will show up during charging, since the value 
is given by register 0x18 with index "BQ27XXX_REG_TTF".

TEST CASE I:  discharging current >0:
POWER_SUPPLY_NAME=bq78z100-0
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_VOLTAGE_NOW=3405000
POWER_SUPPLY_CURRENT_NOW=4000
POWER_SUPPLY_CAPACITY=28
POWER_SUPPLY_CAPACITY_LEVEL=Normal
POWER_SUPPLY_TEMP=259
POWER_SUPPLY_TIME_TO_EMPTY_NOW=1611000
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CHARGE_FULL=6494000
POWER_SUPPLY_CHARGE_FULL_DESIGN=600
POWER_SUPPLY_CYCLE_COUNT=1
POWER_SUPPLY_ENERGY_NOW=0
POWER_SUPPLY_POWER_AVG=65535
POWER_SUPPLY_HEALTH=Good
POWER_SUPPLY_MANUFACTURER=Texas Instruments

TEST CASE II : discharging current =0:
POWER_SUPPLY_NAME=bq78z100-0
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_VOLTAGE_NOW=3405000
POWER_SUPPLY_CURRENT_NOW=0
POWER_SUPPLY_CAPACITY=28
POWER_SUPPLY_CAPACITY_LEVEL=Normal
POWER_SUPPLY_TEMP=260
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CHARGE_FULL=6494000
POWER_SUPPLY_CHARGE_FULL_DESIGN=600
POWER_SUPPLY_CYCLE_COUNT=1
POWER_SUPPLY_ENERGY_NOW=0
POWER_SUPPLY_POWER_AVG=0

I also asked to check other exposed properties and to provide a dump of the 
power-supply uevent in commit message or cover letter to verify chip works as 
expected. I cannot see the dump and you are exposing at least one property that 
always reports -ENODATA. I intentionally will not point out the exact property, 
so that you have to properly test your patch before submitting.

Thanks,

2021-03-04 Thread LI Qingwu
Changes in V5:

1. Change [BQ27XXX_REG_TTES] from INVALID_REG_ADDR to 0x1c,
the StandbyTimeToEmpty command of bq78z100.
2. Add [BQ27XXX_REG_RC] = 0x10. the RemainingCapacity command of
bq78z100.
3. Set [BQ27XXX_REG_AE] to INVALID_REG_ADDR, support by bq78z100.
4. Delete property POWER_SUPPLY_PROP_TIME_TO_EMPTY_AVG, not support
by bq78z100
