bq27xxx: add voltage min design for bq27000 and bq27200

2024-12-18T23:42:21Z

The bq27x00 gauges have an EEPROM register which contains the value of the voltage that should be considered to be zero battery capacity. Expose this to userspace using the VOLTAGE_MIN_DESIGN property. Tested on Nokia N900 with bq27200. Signed-off-by: Sicelo A.

power: supply: bq27xxx: Move health reading out of update loop

2024-04-01T10:29:44Z

Most of the functions that read values return a status and put the value itself in an a function parameter. Update health reading to match. As health is not checked for changes as part of the update loop, remove the read of this from the periodic update loop. This saves I2C/1W bandwidth. It also means we do not have to cache it, fresh values are read when requested.

power: supply: bq27xxx: Stop and start delayed work in suspend and resume

2023-11-15T22:13:26Z

This driver uses delayed work to perform periodic battery state read out. This delayed work is not stopped across suspend and resume cycle. The read out can occur early in the resume cycle. In case of an I2C variant of this hardware, that read out triggers I2C transfer. That I2C transfer may happen while the I2C controller is still suspended, which produces a WARNING in the kernel log. Fix this by introducing trivial PM ops, which stop the delayed work before the system enters suspend, and schedule the delayed work right after the system resumes.
