Common properties for temperature sensors that are not handled by drivers.
Zero values in degrees K(-273 in degrees C)in thermal thresholds will
be ignored
compatible: "cros-ec,temp-sensors"
child-binding:
description: Named temperature sensor node
properties:
sensor:
type: phandle
required: true
description:
A pointer to a coresponding temperature sensor node.
power-good-pin:
type: phandle
description:
If this sensor will be unpowered some of the time, provide an input GPIO
which can be referenced to detect whether the sensor is powered before
reading.
temp_fan_off:
type: int
description:
Temperature threshold in degrees C when no active cooling
is needed
temp_fan_max:
type: int
description:
Temperature threshold in degrees C when max active cooling
is needed
temp_host_warn:
type: int
description:
Temperature threshold in degrees C of thermal warn.
Temperatures above the thermal warn threshold generate a
request to the AP to throttle itself.
temp_host_high:
type: int
description:
Temperature threshold in degrees C of thermal high.
Temperatures above the thermal high threshold cause the EC to
assert a signal (usually PROCHOT) to the AP and force the AP to
throttle.
temp_host_halt:
type: int
description:
Temperature threshold in degrees C that forces AP to shutdown
due to thermal reason
temp_host_release_warn:
type: int
description:
Temperature release threshold in degrees C of thermal warn
temp_host_release_high:
type: int
description:
Temperature release threshold in degrees C of thermal high
temp_host_release_halt:
type: int
description:
Temperature release threshold in degrees C of thermal shutdown
