menuconfig PLATFORM_EC_TEMP_SENSOR
bool "Temperature sensors"
default y
depends on DT_HAS_CROS_EC_TEMP_SENSORS_ENABLED
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_TEMP_SENSOR_POWER
bool "Temperature sensors are not always powered on"
help
If enabled, temperature sensors require enabling power rail before
being read. Enabling it requires to define a pin enabling the power
as GPIO_TEMP_SENSOR_POWER.
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"
default y
depends on DT_HAS_CROS_EC_THERMISTOR_ENABLED
depends on ADC
help
Enables support for thermistors (resistor whose resistance is
strongly dependent on temperature) as temperature-sensor type.
config PLATFORM_EC_TEMP_SENSOR_PCT2075
bool "PCT2075 support"
default y
depends on DT_HAS_NXP_PCT2075_ENABLED
help
Enables support for the CrosEC PCT2075 sensor, an i2c peripheral
temperature sensor from NXP.
config PLATFORM_EC_TEMP_SENSOR_SB_TSI
bool "SB TSI support"
default y
depends on DT_HAS_AMD_SB_TSI_ENABLED
help
Enables support for the Side Band Temperature Sensor Interface,
an i2c peripheral available on AMD platforms.
config PLATFORM_EC_TEMP_SENSOR_TMP112
bool "TMP112 support"
default y
depends on DT_HAS_CROS_EC_TEMP_SENSOR_TMP112_ENABLED
help
Enables support for the CrosEC TMP112 driver, an i2c peripheral
temperature sensor from TI.
config PLATFORM_EC_TEMP_SENSOR_F75303
bool "F75303 support"
default y
depends on DT_HAS_CROS_EC_TEMP_SENSOR_F75303_ENABLED
help
Enables support for the CrosEC F75303 driver, an i2c peripheral
temperature sensor from TI.
endif # PLATFORM_EC_TEMP_SENSOR
config PLATFORM_EC_TEMP_SENSOR_FIRST_READ_DELAY
bool "Enable a delay before reading temperature seensors"
help
Enables a delay on the first read of temperature sensors after
the EC powers on. This allows for setting of any power rails that
control the temperature sensors on the platform.
if PLATFORM_EC_TEMP_SENSOR_FIRST_READ_DELAY
config PLATFORM_EC_TEMP_SENSOR_FIRST_READ_DELAY_MS
int "Temperature sensor read delay time"
default 500
help
Sets the delay time, in milliseconds, before the first the EC will
read any temperature sensors and perform any thermal management.
endif # PLATFORM_EC_TEMP_SENSOR_FIRST_READ_DELAY
config PLATFORM_EC_FAN
bool "Fan support"
default y
depends on DT_HAS_CROS_EC_FANS_ENABLED
select PWM
select SENSOR
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).
config PLATFORM_EC_CUSTOM_FAN_CONTROL
bool "Fan custom control support"
default n
help
Enable fan custom control to let projects define
their own fan control mechanism by EC.
if PLATFORM_EC_FAN
config PLATFORM_EC_NUM_FANS
int "Number of fans"
default 1
help
Declare the number of fans supported on this board and avilable
for control through fan APIs.
endif # PLATFORM_EC_FAN
config PLATFORM_EC_FAN_BYPASS_SLOW_RESPONSE
bool "Enable fan slow response control mechanism"
default n
help
A specific type of fan needs a longer time to output the TACH
signal to EC after EC outputs the PWM signal to the fan.
During this period, the driver will read two consecutive RPM = 0.
In this case, don't step the PWM duty too aggressively.
