+Tegra124 SOCTHERM thermal management system
+
+The SOCTHERM IP block contains thermal sensors, support for polled
+or interrupt-based thermal monitoring, CPU and GPU throttling based
+on temperature trip points, and handling external overcurrent
+notifications. It is also used to manage emergency shutdown in an
+overheating situation.
+
+Required properties :
+- compatible : "nvidia,tegra124-soctherm".
+- reg : Should contain 1 entry:
+  - SOCTHERM register set
+- interrupts : Defines the interrupt used by SOCTHERM
+- clocks : Must contain an entry for each entry in clock-names.
+  See ../clocks/clock-bindings.txt for details.
+- clock-names : Must include the following entries:
+  - tsensor
+  - soctherm
+- resets : Must contain an entry for each entry in reset-names.
+  See ../reset/reset.txt for details.
+- reset-names : Must include the following entries:
+  - soctherm
+- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
+    of this property. See <dt-bindings/thermal/tegra124-soctherm.h> for a
+    list of valid values when referring to thermal sensors.
+
+
+Example :
+
+	soctherm@0,700e2000 {
+		compatible = "nvidia,tegra124-soctherm";
+		reg = <0x0 0x700e2000 0x0 0x1000>;
+		interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&tegra_car TEGRA124_CLK_TSENSOR>,
+			<&tegra_car TEGRA124_CLK_SOC_THERM>;
+		clock-names = "tsensor", "soctherm";
+		resets = <&tegra_car 78>;
+		reset-names = "soctherm";
+
+		#thermal-sensor-cells = <1>;
+	};
+
+Example: referring to thermal sensors :
+
+       thermal-zones {
+                cpu {
+                        polling-delay-passive = <1000>;
+                        polling-delay = <1000>;
+
+                        thermal-sensors =
+                                <&soctherm TEGRA124_SOCTHERM_SENSOR_CPU>;
+                };
+	};
