Subject: [RFC PATCH 11/14] arm: dts: add omap5 GPU thermal data
Date: Fri, 23 Aug 2013 19:15:52 -0400

This patch changes a dtsi file to contain the thermal data
for GPU domain on OMAP5 and later SoCs. This data will
enable a thermal shutdown at 125C.

This thermal data can be reused across TI SoC devices.
