From 28c90169f1d5eabf503e356c76bf49a67aef4cc0 Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Fri, 16 Aug 2013 11:57:33 -0400 Subject: arm: dts: add omap5 GPU thermal data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
