From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chen-Yu Tsai Subject: [PATCH v3 3/9] ARM: dts: sun7i: Add cpu thermal zones to dtsi Date: Mon, 12 Jan 2015 12:34:03 +0800 Message-ID: <1421037249-28461-4-git-send-email-wens@csie.org> References: <1421037249-28461-1-git-send-email-wens@csie.org> Return-path: In-Reply-To: <1421037249-28461-1-git-send-email-wens@csie.org> Sender: linux-pm-owner@vger.kernel.org To: Maxime Ripard , Dmitry Torokhov , Zhang Rui , Eduardo Valentin Cc: Chen-Yu Tsai , Hans de Goede , linux-input@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-pm@vger.kernel.org List-Id: linux-input@vger.kernel.org The core temperature sensor now supports thermal zones. Add a thermal zone mapping for the cpus with passive cooling (cpufreq throttling).
