To ensure that data is consistent across multiple sequential calls to `fuel_gauge_get_prop`, sensor_fetch is only called if a certain time period has passed since the previous sampling. This emulates the tick-based sampling of most dedicated fuel-gauge devices. Signed-off-by: Jordan Yates <[email protected]> tick
Instead of explicitly specifying the source for the voltage and current channels, specify primary and secondary data sources. If the requested sensor channel does not exist on the primary source, the secondary source will be tried. Signed-off-by: Jordan Yates <[email protected]>
Choose whether the data sources should be queried by the generic sensor channels (`SENSOR_CHAN_VOLTAGE`, etc), or the fuel guage specific channels (`SENSOR_CHAN_GAUGE_*`). Signed-off-by: Jordan Yates <[email protected]>
Add support for the `FUEL_GAUGE_TEMPERATURE` property. Signed-off-by: Jordan Yates <[email protected]>
Query the configured data sources for capacity and soc information before falling back to the composite fuel gauge configuration. This means the battery properties are no longer required. Signed-off-by: Jordan Yates <[email protected]>

Depends on #88395
The motivation for this PR is the desire to access core functionality of the existing in-tree nPM1300 driver (which implements the sensor API using
SENSOR_CHAN_GAUGE_*channels) through the fuel gauge API, together with extending it to support SoC lookup.
