menuconfig PLATFORM_EC_TEMP_SENSOR
bool "Temperature sensors"
help
Support for temperature sensors. Once enabled, "temps" console
command and EC_CMD_TEMP_SENSOR_GET_INFO host command are available.
if PLATFORM_EC_TEMP_SENSOR
config PLATFORM_EC_DPTF
bool "Dynamic Platform and Thermal Framework"
default y if PLATFORM_EC_ACPI
help
Enables the Dynamic Platform and Thermal Framework (DPTF). DPTF
exposes the temperature sensors and the fan controls to the
Applicaiton Processor (AP) using Advanced Configuration and Power
Interface (ACPI). This permits the AP to control thermal management
independent of the EC.
Even when DPTF is enabled, the EC still monitors temperature sensors
and will take corrective actions for high temperatures such as turning
on the fans or powering down the AP.
config PLATFORM_EC_THERMISTOR
bool "Thermistor support"
depends on PLATFORM_EC_ADC
help
Enables support for thermistors (resistor whose resistance is
strongly dependent on temperature) as temperature-sensor type.
config PLATFORM_EC_STEINHART_HART_3V0_22K6_47K_4050B
bool "Steinhart-hart 3V0_22K6_47K_4050B"
depends on PLATFORM_EC_THERMISTOR
help
Enables support for measuring temperature using the Steinhart-Hart
equation model and the thermistor configured with the following
circuit configuration:
-3.0V reference voltage
-22.6 kilohm fixed resistor, connected to the reference voltage
-47 kilohm thermistor reference resistance at 25 C
-4050 B-constant (thermistor sensitivity)
config PLATFORM_EC_STEINHART_HART_3V3_13K7_47K_4050B
bool "Steinhart-hart 3V3_13K7_47K_4050B"
depends on PLATFORM_EC_THERMISTOR
help
Enables support for measuring temperature using the Steinhart-Hart
equation model and the thermistor configured with the following
circuit configuration:
-3.3V reference voltage
-13.7 kilohm fixed resistor, connected to the reference voltage
-47 kilohm thermistor reference resistance at 25 C
-4050 B-constant (thermistor sensitivity)
config PLATFORM_EC_STEINHART_HART_3V3_30K9_47K_4050B
bool "Steinhart-hart 3V3_30K9_47K_4050B"
depends on PLATFORM_EC_THERMISTOR
help
Enables support for measuring temperature using the Steinhart-Hart
equation model and the thermistor configured with the following
circuit configuration:
-3.3V reference voltage
-30.9 kilohm fixed resistor, connected to the reference voltage
-47 kilohm thermistor reference resistance at 25 C
-4050 B-constant (thermistor sensitivity)
config PLATFORM_EC_STEINHART_HART_3V3_51K1_47K_4050B
bool "Steinhart-hart 3V3_51K1_47K_4050B"
depends on PLATFORM_EC_THERMISTOR
default y
help
Enables support for measuring temperature using the Steinhart-Hart
equation model and the thermistor configured with the following
circuit configuration:
-3.3V reference voltage
-51.1 kilohm fixed resistor, connected to the reference voltage
-47 kilohm thermistor reference resistance at 25 C
-4050 B-constant (thermistor sensitivity)
endif # PLATFORM_EC_TEMP_SENSOR
config PLATFORM_EC_FAN
bool "Fan support"
depends on PLATFORM_EC_PWM
help
Enables support for fans. Allows periodic thermal task to
automatically set the fan speed (control temperature).
Once enabled fanduty, fanset, faninfo, fanauto consol command and
EC_CMD_PWM_GET_FAN_TARGET_RPM, EC_CMD_PWM_SET_FAN_TARGET_RPM,
EC_CMD_PWM_SET_FAN_DUTY, EC_CMD_THERMAL_AUTO_FAN_CTRL are
available. Also enables a periodic task (1s) to verify fan is
running (is not stalled).
