From 0fe4d2181cc4cb3eba303c0e03f878d2558d0f3a Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Fri, 31 Mar 2017 20:03:04 +0000 Subject: ARM: dts: bcm283x: Add CPU thermal zone with 1 trip point As suggested by Eduardo Valentin this adds the thermal zone for the bcm2835 SoC with its single thermal sensor. We start with the criticial trip point and leave the cooling devices empty since we don't have any at the moment. Since the coefficients could vary depending on the SoC we need to define them separate.
