[PATCH 4.14 21/21] ARM: dts: r8a7793: Correct critical CPU temperature

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chris Paterson <chris.paterson2@renesas.com>

commit 1dfc65cef481ac6af64380f26186d5cc585b46eb upstream.

The R-Car M2N 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.
