+* Thermal Monitoring Unit (TMU) on Freescale QorIQ SoCs
+
+Required properties:
+- compatible : Must include "fsl,qoriq-tmu". The version of the device is
+	determined by the TMU IP Block Revision Register (IPBRR0) at
+	offset 0x0BF8.
+	Table of correspondences between IPBRR0 values and example  chips:
+		Value           Device
+		----------      -----
+		0x01900102      T1040
+- reg : Address range of TMU registers.
+- interrupts : Contains the interrupt for TMU.
+- fsl,tmu-range : The values to be programmed into TTRnCR, as specified by
+	the SoC reference manual. The first cell is TTR0CR, the second is
+	TTR1CR, etc.
+- fsl,tmu-calibration : A list of cell pairs containing temperature
+	calibration data, as specified by the SoC reference manual.
+	The first cell of each pair is the value to be written to TTCFGR,
+	and the second is the value to be written to TSCFGR.
+
+Example:
+
+tmu@f0000 {
+	compatible = "fsl,qoriq-tmu";
