config DPTF_POWER
tristate "DPTF Platform Power Participant"
depends on X86
help
This driver adds support for Dynamic Platform and Thermal Framework
(DPTF) Platform Power Participant device (INT3407) support.
This participant is responsible for exposing platform telemetry:
max_platform_power
platform_power_source
adapter_rating
battery_steady_power
charger_type
To compile this driver as a module, choose M here:
the module will be called dptf_power.
