From c8c876898b2ba09d06151d027485107bb470878f Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Wed, 17 Aug 2016 10:48:45 +0530 Subject: [PATCH] arm: dts: apq8064: Add thermal zones, tsens and qfprom nodes TSENS is part of GCC, hence add TSENS properties as part of GCC node. Also add thermal zones and qfprom nodes. Update GCC bindings doc to mention the possibility of optional TSENS properties that can be part of GCC node.
