From mboxrd@z Thu Jan 1 00:00:00 1970 From: chris.paterson2@renesas.com (Chris Paterson) Date: Thu, 14 Dec 2017 09:08:40 +0000 Subject: [PATCH 2/3] ARM: dts: r8a7791: Correct critical CPU temperature In-Reply-To: <1513242521-11236-1-git-send-email-chris.paterson2@renesas.com> References: <1513242521-11236-1-git-send-email-chris.paterson2@renesas.com> Message-ID: <1513242521-11236-3-git-send-email-chris.paterson2@renesas.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The R-Car M2W 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.
