+* 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";
