Subject: [PATCH v9 3/5] ARM: dts: add RK3288 Thermal data
Date: Sat, 11 Oct 2014 15:29:21 +0800 [thread overview]
Message-ID: <1413012563-7690-4-git-send-email-caesar.wang@rock-chips.com> (raw)
In-Reply-To: <1413012563-7690-1-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.
