power: supply: core: Refactor power_supply_set_input_current_limit_from_supplier()

2023-06-05T07:07:03+00:00

[ Upstream commit 2220af8ca61ae67de4ec3deec1c6395a2f65b9fd ] Some (USB) charger ICs have variants with USB D+ and D- pins to do their own builtin charger-type detection, like e.g. the bq24190 and bq25890 and also variants which lack this functionality, e.g. the bq24192 and bq25892. In case the charger-type; and thus the input-current-limit detection is done outside the charger IC then we need some way to communicate this to the charger IC. In the past extcon was used for this, but if the external detection does e.g. full USB PD negotiation then the extcon cable-types do not convey enough information. For these setups it was decided to model the external charging "brick" and the parameters negotiated with it as a power_supply class-device itself; and power_supply_set_input_current_limit_from_supplier() was introduced to allow drivers to get the input-current-limit this way. But in some cases psy drivers may want to know other properties, e.g. the bq25892 can do "quick-charge" negotiation by pulsing its current draw, but this should only be done if the usb_type psy-property of its supplier is set to DCP (and device-properties indicate the board allows higher voltages). Instead of adding extra helper functions for each property which a psy-driver wants to query from its supplier, refactor power_supply_set_input_current_limit_from_supplier() into a more generic power_supply_get_property_from_supplier() function.

power: supply: add wireless type

2020-08-26T14:53:26+00:00

Currently, power_supply framework supports only Battery, UPS, Mains and USB power_supply_type. Add wireless power_supply_type so that the drivers which supports wireless can register a power supply class device with POWER_SUPPLY_TYPE_WIRELESS.

power: supply: Support battery temperature device-tree properties

2020-08-25T17:24:37+00:00

The generic battery temperature properties are already supported by the power-supply core. Let's support parsing of the common battery temperature properties from a device-tree. Signed-off-by: Dmitry Osipenko Signed-off-by: Sebastian Reichel

power: supply: wilco_ec: Add long life charging mode

2020-07-31T12:33:56+00:00

This is a long life mode set in the factory for extended warranty battery, the power charging rate is customized so that battery at work last longer. Presently switching to a different battery charging mode is through EC PID 0x0710 to configure the battery firmware, this operation will be blocked by EC with failure code 0x01 when PLL mode is already in use.
