In bypass charging operation, the charger bypasses the charging path around the integrated converter allowing for a "smart" wall adaptor to perform the power conversion externally. This operational mode is critical for the USB PPS standard of power adaptors and is becoming a common feature in modern charging ICs such as: - BQ25980 - BQ25975 - BQ25960 - LN8000 - LN8410 Signed-off-by: Ricardo Rivera-Matos --- drivers/power/supply/power_supply_sysfs.c | 1 + include/linux/power_supply.h | 1 + 2 files changed, 2 insertions(+) diff --git a/drivers/power/supply/power_supply_sysfs.c b/drivers/power/supply/power_supply_sysfs.c index 6ac88fbee3cb..52c909bae457 100644 --- a/drivers/power/supply/power_supply_sysfs.c +++ b/drivers/power/supply/power_supply_sysfs.c @@ -89,6 +89,7 @@ static const char * const POWER_SUPPLY_CHARGE_TYPE_TEXT[] = { [POWER_SUPPLY_CHARGE_TYPE_ADAPTIVE] = "Adaptive", [POWER_SUPPLY_CHARGE_TYPE_CUSTOM] = "Custom", [POWER_SUPPLY_CHARGE_TYPE_LONGLIFE] = "Long Life", + [POWER_SUPPLY_CHARGE_TYPE_BYPASS] = "Bypass", }; static const char * const POWER_SUPPLY_HEALTH_TEXT[] = { diff --git a/include/linux/power_supply.h b/include/linux/power_supply.h index 86b4d5c4dab9..164779bc7e8f 100644 --- a/include/linux/power_supply.h +++ b/include/linux/power_supply.h @@ -49,6 +49,7 @@ enum { POWER_SUPPLY_CHARGE_TYPE_ADAPTIVE, /* dynamically adjusted speed */ POWER_SUPPLY_CHARGE_TYPE_CUSTOM, /* use CHARGE_CONTROL_* props */ POWER_SUPPLY_CHARGE_TYPE_LONGLIFE, /* slow speed, longer life */ + POWER_SUPPLY_CHARGE_TYPE_BYPASS, /* bypassing the charger */ }; enum {
