[PATCH v6 08/11] arm: dts: apq8064: Add thermal zones, tsens and qfprom nodes

From: Rajendra Nayak <hidden>
Date: 2016-05-05 08:51:46
Also in: linux-arm-msm, linux-pm
Subsystem: arm/qualcomm mailing list, common clk framework, open firmware and flattened device tree bindings, qualcomm clock drivers, the rest · Maintainers: Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Bjorn Andersson, Linus Torvalds

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.
