Subject: [PATCH v15 3/5] ARM: dts: add RK3288 Thermal data
Date: Tue, 28 Oct 2014 16:51:25 +0800	[thread overview]
Message-ID: <1414486287-25498-4-git-send-email-caesar.wang@rock-chips.com> (raw)
In-Reply-To: <1414486287-25498-1-git-send-email-caesar.wang@rock-chips.com>

This patch changes a dtsi file to contain the thermal data
on RK3288 and later SoCs. This data will
enable a thermal shutdown over 120C.
