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_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"
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_TEMP_SENSOR_PCT2075
bool "PCT2075 support"
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"
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"
help
Enables support for the CrosEC TMP112 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
DT_COMPAT_CROS_EC_FANS := cros-ec,fans
config PLATFORM_EC_FAN
bool "Fan support"
default $(dt_compat_enabled,$(DT_COMPAT_CROS_EC_FANS))
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).
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.
