power: supply: core: Add Standard, Adaptive, and Custom charge types
Add "Standard", "Adaptive", and "Custom" modes to the charge_type property, to expand the existing "Trickle" and "Fast" modes. I am adding them in order to support a new Chrome OS device, but these properties should be general enough that they can be used on other devices. The meaning of "Standard" is obvious, but "Adaptive" and "Custom" are more tricky: "Adaptive" means that the charge controller uses some custom algorithm to change the charge type automatically, with no configuration needed. "Custom" means that the charge controller uses the POWER_SUPPLY_PROP_CHARGE_CONTROL_* properties as configuration for some other algorithm. v5 changes: - Split up adding the charge types and adding the POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties into two different commits. v4 changes: - Add documentation for the new properties, and add documentation for the the previously missing charge_control_limit and charge_control_limit_max properties.
