From: Steve Twiss <stwiss.opensource@xxxxxxxxxxx> Add junction temperature monitoring supervisor device driver, compatible with the DA9062 and DA9061 PMICs. A MODULE_DEVICE_TABLE() macro is added. If the PMIC's internal junction temperature rises above TEMP_WARN (125 degC) an interrupt is issued. This TEMP_WARN level is defined as the THERMAL_TRIP_HOT trip-wire inside the device driver. The thermal triggering mechanism is interrupt based and happens when the temperature rises above a given threshold level. The component cannot return an exact temperature, it only has knowledge if the temperature is above or below a given threshold value. A status bit must be polled to detect when the temperature falls below that threshold level again. A kernel work queue is configured to repeatedly poll and detect when the temperature falls below this trip-wire, between 1 and 10 second intervals (defaulting at 3 seconds). This first level of temperature supervision is intended for non-invasive temperature control, where the necessary measures for cooling the system down are left to the host software.
