776 tristate "ChromeOS EC based USBPD charger"
777 depends on CROS_USBPD_NOTIFY
779 Say Y here to enable ChromeOS EC based USBPD charger
780 driver. This driver gets various bits of information about
781 what is connected to USB PD ports from the EC and converts
782 that into power_supply properties.
784 config CHARGER_CROS_PCHG
785 tristate "ChromeOS EC based peripheral charger"
786 depends on MFD_CROS_EC_DEV
787 default MFD_CROS_EC_DEV
789 Say Y here to enable ChromeOS EC based peripheral charge driver.
790 This driver gets various information about the devices connected to
791 the peripheral charge ports from the EC and converts that into
792 power_supply properties.
794 config CHARGER_SC2731
795 tristate "Spreadtrum SC2731 charger driver"
796 depends on MFD_SC27XX_PMIC || COMPILE_TEST
798 Say Y here to enable support for battery charging with SC2731
801 config FUEL_GAUGE_SC27XX
802 tristate "Spreadtrum SC27XX fuel gauge driver"
803 depends on MFD_SC27XX_PMIC || COMPILE_TEST
806 Say Y here to enable support for fuel gauge with SC27XX
809 config CHARGER_UCS1002
810 tristate "Microchip UCS1002 USB Port Power Controller"
816 Say Y to enable support for Microchip UCS1002 Programmable
817 USB Port Power Controller with Charger Emulation.
819 config CHARGER_BD99954
820 tristate "ROHM bd99954 charger driver"
824 Say Y here to enable support for getting battery and charger
825 information and altering charger configurations from the ROHM
829 tristate "Wilco EC based charger for ChromeOS"
832 Say Y here to enable control of the charging routines performed
833 by the Embedded Controller on the Chromebook named Wilco. Further
834 information can be found in
835 Documentation/ABI/testing/sysfs-class-power-wilco
838 tristate "RN5T618 charger/fuel gauge support"
839 depends on MFD_RN5T618
840 depends on RN5T618_ADC
843 Say Y here to have support for RN5T618 PMIC family fuel gauge and charger.
844 This driver can also be built as a module. If so, the module will be
845 called rn5t618_power.
847 config BATTERY_ACER_A500
848 tristate "Acer Iconia Tab A500 battery driver"
849 depends on MFD_ACER_A500_EC
851 Say Y to include support for Acer Iconia Tab A500 battery fuel gauge.
853 config BATTERY_SURFACE
854 tristate "Battery driver for 7th-generation Microsoft Surface devices"
855 depends on SURFACE_AGGREGATOR_REGISTRY
857 Driver for battery devices connected via/managed by the Surface System
858 Aggregator Module (SSAM).
860 This driver provides battery-information and -status support for
861 Surface devices where said data is not exposed via the standard ACPI
862 devices. On those models (7th-generation), battery-information is
863 instead handled directly via SSAM client devices and this driver.
865 Say M or Y here to include battery status support for 7th-generation
866 Microsoft Surface devices, i.e. Surface Pro 7, Surface Laptop 3,
867 Surface Book 3, and Surface Laptop Go.
869 config CHARGER_SURFACE
870 tristate "AC driver for 7th-generation Microsoft Surface devices"
871 depends on SURFACE_AGGREGATOR_REGISTRY
873 Driver for AC devices connected via/managed by the Surface System
874 Aggregator Module (SSAM).
876 This driver provides AC-information and -status support for Surface
877 devices where said data is not exposed via the standard ACPI devices.
878 On those models (7th-generation), AC-information is instead handled
879 directly via a SSAM client device and this driver.
881 Say M or Y here to include AC status support for 7th-generation
882 Microsoft Surface devices, i.e. Surface Pro 7, Surface Laptop 3,
883 Surface Book 3, and Surface Laptop Go.
885 config BATTERY_UG3105
886 tristate "uPI uG3105 battery monitor driver"
889 Battery monitor driver for the uPI uG3105 battery monitor.
891 Note the uG3105 is not a full-featured autonomous fuel-gauge. Instead
892 it is expected to be use in combination with some always on
893 microcontroller reading its coulomb-counter before it can wrap
894 (it must be read every 400 seconds!).
896 Since Linux does not monitor coulomb-counter changes while the
897 device is off or suspended, the functionality of this driver is
898 limited to reporting capacity only.
