From 36c2cb1830e0799f7f35c1429404c842daa8996d Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Fri, 14 Apr 2017 23:42:28 +0200 Subject: ARM: dts: BCM5301X: Add CPU thermal sensor and zone MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This uses CPU thermal sensor available on every Northstar chipset to monitor temperature. We don't have any cooling or throttling so only a critical trip was added.
