From mboxrd@z Thu Jan 1 00:00:00 1970 From: eduardo.valentin@ti.com (Eduardo Valentin) Date: Wed, 17 Jul 2013 11:02:46 -0400 Subject: [PATCH 5/8] arm: dts: add omap4430 thermal data In-Reply-To: <1374073374-30946-1-git-send-email-eduardo.valentin@ti.com> References: <1374073374-30946-1-git-send-email-eduardo.valentin@ti.com> Message-ID: <1374073374-30946-11-git-send-email-eduardo.valentin@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch changes the dtsi entry on omap4430 to contain the thermal data. This data will enable the passive cooling with CPUfreq cooling device at 100C and the system will do a thermal shutdown at 125C.
