803 that into power_supply properties.
805 config CHARGER_CROS_PCHG
806 tristate "ChromeOS EC based peripheral charger"
807 depends on MFD_CROS_EC_DEV
808 default MFD_CROS_EC_DEV
810 Say Y here to enable ChromeOS EC based peripheral charge driver.
811 This driver gets various information about the devices connected to
812 the peripheral charge ports from the EC and converts that into
813 power_supply properties.
815 config CHARGER_SC2731
816 tristate "Spreadtrum SC2731 charger driver"
817 depends on MFD_SC27XX_PMIC || COMPILE_TEST
819 Say Y here to enable support for battery charging with SC2731
822 config FUEL_GAUGE_SC27XX
823 tristate "Spreadtrum SC27XX fuel gauge driver"
824 depends on MFD_SC27XX_PMIC || COMPILE_TEST
827 Say Y here to enable support for fuel gauge with SC27XX
830 config CHARGER_UCS1002
831 tristate "Microchip UCS1002 USB Port Power Controller"
837 Say Y to enable support for Microchip UCS1002 Programmable
838 USB Port Power Controller with Charger Emulation.
840 config CHARGER_BD99954
841 tristate "ROHM bd99954 charger driver"
845 Say Y here to enable support for getting battery and charger
846 information and altering charger configurations from the ROHM
850 tristate "Wilco EC based charger for ChromeOS"
853 Say Y here to enable control of the charging routines performed
854 by the Embedded Controller on the Chromebook named Wilco. Further
855 information can be found in
856 Documentation/ABI/testing/sysfs-class-power-wilco
859 tristate "RN5T618 charger/fuel gauge support"
860 depends on MFD_RN5T618
861 depends on RN5T618_ADC
864 Say Y here to have support for RN5T618 PMIC family fuel gauge and charger.
865 This driver can also be built as a module. If so, the module will be
866 called rn5t618_power.
868 config BATTERY_ACER_A500
869 tristate "Acer Iconia Tab A500 battery driver"
870 depends on MFD_ACER_A500_EC
872 Say Y to include support for Acer Iconia Tab A500 battery fuel gauge.
874 config BATTERY_SURFACE
875 tristate "Battery driver for 7th-generation Microsoft Surface devices"
876 depends on SURFACE_AGGREGATOR_REGISTRY
878 Driver for battery devices connected via/managed by the Surface System
879 Aggregator Module (SSAM).
881 This driver provides battery-information and -status support for
882 Surface devices where said data is not exposed via the standard ACPI
883 devices. On those models (7th-generation), battery-information is
884 instead handled directly via SSAM client devices and this driver.
886 Say M or Y here to include battery status support for 7th-generation
887 Microsoft Surface devices, i.e. Surface Pro 7, Surface Laptop 3,
888 Surface Book 3, and Surface Laptop Go.
890 config CHARGER_SURFACE
891 tristate "AC driver for 7th-generation Microsoft Surface devices"
892 depends on SURFACE_AGGREGATOR_REGISTRY
894 Driver for AC devices connected via/managed by the Surface System
895 Aggregator Module (SSAM).
897 This driver provides AC-information and -status support for Surface
898 devices where said data is not exposed via the standard ACPI devices.
899 On those models (7th-generation), AC-information is instead handled
900 directly via a SSAM client device and this driver.
902 Say M or Y here to include AC status support for 7th-generation
903 Microsoft Surface devices, i.e. Surface Pro 7, Surface Laptop 3,
904 Surface Book 3, and Surface Laptop Go.
906 config BATTERY_UG3105
907 tristate "uPI uG3105 battery monitor driver"
910 Battery monitor driver for the uPI uG3105 battery monitor.
912 Note the uG3105 is not a full-featured autonomous fuel-gauge. Instead
913 it is expected to be use in combination with some always on
914 microcontroller reading its coulomb-counter before it can wrap
915 (it must be read every 400 seconds!).
917 Since Linux does not monitor coulomb-counter changes while the
918 device is off or suspended, the functionality of this driver is
919 limited to reporting capacity only.
