| Support for temperature sensors. Once enabled, "temps" console |

| 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 |

| 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_DPTF_PRINTS |
| bool "Dynamic Platform and Thermal Framework debug prints" |
| default n |
| help |
| Enables debug prints for DPTF. These are not needed in normal operation |
| and result in a large amount of console prints when enabled. |

| strongly dependent on temperature) as temperature-sensor type. |

| During this period, the driver will read two consecutive RPM = 0. |
| In this case, don't step the PWM duty too aggressively. |
