If anyone has any objections, please let me know. ------------------ commit fcab5651fae4258a993170b7aaf443adbd3d4d84 upstream The R-Car H2 hardware manual states that Tc = –40°C to +105°C. The thermal sensor has an accuracy of ±5°C and there can be a temperature difference of 1 or 2 degrees between Tjmax and the thermal sensor due to the location of the latter. This means that 95°C is a safer value to use.
