+Subject: ARM: dts: r8a7790: Correct critical CPU temperature
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
