From mboxrd@z Thu Jan 1 00:00:00 1970 From: mperttunen@nvidia.com (Mikko Perttunen) Date: Thu, 21 Aug 2014 13:17:21 +0300 Subject: [PATCH v5 3/4] ARM: tegra: Add thermal trip points for Jetson TK1 In-Reply-To: <1408616242-21009-1-git-send-email-mperttunen@nvidia.com> References: <1408616242-21009-1-git-send-email-mperttunen@nvidia.com> Message-ID: <1408616242-21009-4-git-send-email-mperttunen@nvidia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This adds critical trip points to the Jetson TK1 device tree. The device will do a controlled shutdown when either the CPU, GPU or MEM thermal zone reaches 101 degrees Celsius.
