Subject: ARM: dts: r8a7790: Correct critical CPU temperature
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fcab5651fae4258a993170b7aaf443adbd3d4d84;p=linux.git

ARM: dts: r8a7790: Correct critical CPU temperature

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.
