    Subject[PATCH 4.14 109/143] ARM: dts: r8a7790: Correct critical CPU temperature
    Date
    4.14-stable review patch.  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.

    Fixes: a8b805f3606f7af7 ("ARM: dts: r8a7790: enable to use thermal-zone")
