The .thermal_init needs to be delayed a short amount of time to allow for the TEMP register to contain something useful. If it's not delayed these warnings are common during boot: thermal thermal_zone0: failed to read out thermal zone (-5) thermal thermal_zone1: failed to read out thermal zone (-5) thermal thermal_zone2: failed to read out thermal zone (-5) The warnings are triggered by the first call to .get_temp() while the TEMP register contains 0 and rcar_gen3_thermal_get_temp() returns -EIO since a TEMP value of 0 will result in a temperature reading which is out of specifications. This should have been done in the initial commit which adds the driver as the same issue was found and corrected for r8a7795.
