Adds a POWER_SUPPLY_CHARGE_TYPE_BYPASS option to the POWER_SUPPLY_PROP_CHARGE_TYPE property to facilitate bypass charging operation. 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 <rriveram@opensource.cirrus.com> --- Documentation/ABI/testing/sysfs-class-power | 7 +++++-- drivers/power/supply/power_supply_sysfs.c | 1 + include/linux/power_supply.h | 1 + 3 files changed, 7 insertions(+), 2 deletions(-)
