Subject: [PATCH v7 3/5] ARM: dts: add RK3xxx CPU Thermal data
Date: Sun, 28 Sep 2014 18:38:11 +0800	[thread overview]
Message-ID: <1411900693-30484-4-git-send-email-caesar.wang@rock-chips.com> (raw)
In-Reply-To: <1411900693-30484-1-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 125C.
