[PATCH 4.14 109/143] ARM: dts: r8a7790: Correct critical CPU temperature

[Greg Kroah-Hartman]

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 = â40ÂC to +105ÂC. The
thermal sensor has an accuracy of Â5ÂC 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 95ÂC is a safer value to use.
