TEMP register to contain something useful. If it's not delayed theses
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. Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx>
