Many fuel gauge ICs offer a battery cutoff/shipping mode functionality that cutoff charge from the battery. This is often useful for preserving battery charge on devices while in storage. Add battery cutoff support to the fuel gauge API with a generic default SBS driver showing an example of support in tests. Signed-off-by: Aaron Massey <aaronmassey@google.com>

Properties for fuel-gauges that may control battery cutoff, this is common in SBS-compliant or
|
|
similarly smart battery fuel gauges.
|
|
|
|
Note: These properties are to be used with meaningful defaults in fuel gauge ICs that can cut off
|
|
their associated battery from the system. See the default fuel gauge SBS Gauge compatible as an
|
|
example.
