839 depends on SURFACE_AGGREGATOR_REGISTRY
841 Driver for battery devices connected via/managed by the Surface System
842 Aggregator Module (SSAM).
844 This driver provides battery-information and -status support for
845 Surface devices where said data is not exposed via the standard ACPI
846 devices. On those models (7th-generation), battery-information is
847 instead handled directly via SSAM client devices and this driver.
849 Say M or Y here to include battery status support for 7th-generation
850 Microsoft Surface devices, i.e. Surface Pro 7, Surface Laptop 3,
851 Surface Book 3, and Surface Laptop Go.
