From 9774d96beb2a6454760a0cf5ff8f8f1ce56fc425 Mon Sep 17 00:00:00 2001 From: Caesar Wang Date: Mon, 24 Nov 2014 12:59:00 +0800 Subject: [PATCH] ARM: dts: rockchip: add RK3288 Thermal data This patch changes a dtsi file to contain the thermal data on RK3288 and later SoCs. This data will enable a thermal shutdown over 90C.
