- title: Battery driver for CW2015 shuntless fuel gauge by CellWise.
- maintainers:
- - Tobias Schramm <t.schramm@manjaro.org>
- description: |
- The driver can utilize information from a simple-battery linked via a
- phandle in monitored-battery. If specified the driver uses the
- charge-full-design-microamp-hours property of the battery.
